I am getting this error message when I start Eclipse Helios on Windows 7:
Failed to create the Java Virtual Machine
My eclipse.ini looks as follows:
-startup
plugins/org.eclipse.equinox.launcher_1.1.0.v20100507.jar
-vm
P:\Programs\jdk1.6\bin
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.0.v20100503
-product
org.eclipse.epp.package.jee.product
--launcher.defaultAction
openFile
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
512m
--launcher.defaultAction
openFile
-vmargs
-Dosgi.requiredJavaVersion=1.5
-Xms120m
-Xmn100m
-Xmx1024m
My JAVA_HOME is correctly set as far as I can tell. How can I fix this?
Things I have tried so far:
Adding the full path to javaw.exe
-vm
P:\Programs\jdk1.6\bin\\bin\javaw.exe
Removing the -vm option altogether
Removing --launcher.XXMaxPermSize fixes the issue, but it causes permgen errors
Removing the value 512 of --launcher.XXMaxPermSize fixes the issue, but it causes permgen errors
Reducing -Xmx to 512m also fixes the issue.
Why can I not use '1024m' for '-Xmx' and '--launcher.XXMaxPermSize'?
1. Open the eclipse.ini file from your eclipse folder,see the picture below.
2. Open eclipse.ini in Notepad or any other text-editor application, Find the line -Xmx256m (or -Xmx1024m). Now change the default value 256m (or 1024m) to 512m. You also need to give the exact java installed version (1.6 or 1.7 or other).
Like This:
-Xmx512m
-Dosgi.requiredJavaVersion=1.6
OR
-Xmx512m
-Dosgi.requiredJavaVersion=1.7
OR
-Xmx512m
-Dosgi.requiredJavaVersion=1.8
Then it works well for me.
Try to add
-vm
D:\Java\jdk1.6.0_29\bin\javaw.exe
FYI: Refer sunblog
For others who might have problems with Java 7, as per Eclipse Wiki - eclipse.ini vm_value (windows example)
This might not work on all systems. If you encounter "Java was started but returned exit code=1" error while starting the eclipse, modify the -vm argument to point to jvm.dll
e.g.
-vm
C:\Program Files\Java\jre7\bin\client\jvm.dll
Also note that
The -vm option must occur before the -vmargs option, since everything after -vmargs is passed directly to the JVM
Try removing the -vm P:\Programs\jdk1.6\bin lines.
Also, a general recommendation: set -Dosgi.requiredJavaVersion=1.6, not 1.5.
I know this is pretty old now but I have just had the same issue and the problem was I was allocating to much memory to eclipse that it could not get hold of. So open eclipse.ini and lower the amount of memory that is being allocated to -Xmx XXMaxPermSize I changed mine to -Xmx512m and XXMaxPermSize256m
I removed eclipse.ini. I encountered this issue and removing the ini file solved it.
Open the eclipse.ini file from your eclipse folder.
It has some of add on configuration . Find the line –launcher.XXMaxPermSize. Now remove the the default value 256m and save it.
Open folder with Eclipse.exe and find eclipse.ini file
Replace -vmargs by your current real path of javaw.exe: *-vm
“c:\Program Files\Java\jdk1.7.0_07\bin\javaw.exe”*
-startup
plugins/org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar

-Dosgi.requiredJavaVersion=1.6
-Xms40m
-Xmx768m
-Declipse.buildId=v21.1.0-569685
I found a very easy solution for this. Just delete eclipse.ini file, but backup first. I had this same problem many times and finally I deleted this and I no more have the problem.
It also increased loading time. Now my Eclipse starts faster than earlier.
You can also solve this issue by removing the value "256m" under the line "-launcher.XXMaxPermSize”.
Open the ecplise.ini file which is located in the eclipse installation folder.
Find & Replace the line -vmargs with -vm D:\jdk1.6.0_23\bin\javaw.exe OR just remove the line -vmargs and save it . Now the problem is getting solved
In STS.conf file you need to check two important things to avoid create/allocate jvm issue
1. Give the exact jdk install location:
--vm C:\Program Files\Java\jdk1.7.0_01\jre\bin\javaw.exe
2. You need to give the exact java installed version:
--Dosgi.requiredJavaVersion=1.7
3. Try to reduce the memory size:
--XX:MaxPermSize=256m
After trying the above solution of reducing the memory, Eclipse starts working but hangs every time while loading the plugins from the work-space specially at org.eclipse.debug.core.
I found the solution here, Eclipse hangs at Splash Screen, and want share it. Hopefully it can help others as well.
Make sure eclipse.ini do not have multiple entry and used vm entry before vmargs:
-vm
D:/java/jdk1.8.0_65/bin/javaw.exe
-vmargs
-Dosgi.requiredJavaVersion=1.8
-Dosgi.instance.area.default=#user.home/eclipse-workspace
-XX:+UseG1GC
-XX:+UseStringDeduplication
-Dosgi.requiredJavaVersion=1.8
-Xms256m
-Xmx1024m
Try this one:
-startup plugins/org.eclipse.equinox.launcher_1.1.1.R36x_v20101122_1400.jar
--launcher.library plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.2.R36x_v20101222
-showsplash org.eclipse.platform
--launcher.XXMaxPermSize 256m
--launcher.defaultAction openFile
-vm F:\Program Files\jdk1.6\bin\javaw.exe
-vmargs
-Xms512m
-Xmx512m
-XX:+UseParallelGC
-XX:PermSize=256M
-XX:MaxPermSize=512M
Quick fix:
Change -Xmx1024m to -Xmx512m in eclipse.ini (file located at the same level where eclipse.exe is present). And it will work like a charm.
The simple way to fix this problem is just to delete or rename your eclipse.ini file. Try it first. If this method does not resolve your problem, try the solutions described below.
Other ways to fix it:
Solution 1
Add a string into the eclipse.ini file which change a destination of the javaw.exe file. The main thing is that this string must be placed above the string "-vmargs"!
-vm
C:\Program Files\Java\jdk1.6.0_22\bin\javaw.exe
Solution 2
Remove the value of –launcher.XXMaxPermSize, like 256m.
Solution 3
Remove or decrease the values of Xms and Xmx:
-Xms384m
-Xmx384m
This may work:
Open eclipse.ini file and paste below lines at the end of the lines.
-vmargs
-Xms40m
-Xmx512m
-XX:MaxPermSize=256m
After adding -vm in eclipse.ini as shown below worked for me. Add it before -vmargs do not remove it
-vm
C:\apps\Java\jdk1.8.0_92\bin\javaw.exe
-vmargs
There was a jdk update which was causing this issue.
The proper solution to your problem is to add the -vm line pointing to jvm.dll file of your Java folder in ini fie.
-vm
C:\Program Files\Java\jre1.8.0_202\bin\server\jvm.dll
/*there is no dquote for path, and path points to right java version folder mentioned in ini file*/
If the above fix is not fruitful, then do not attempt anything else. Most of the advice in this thread is misguided. Some of these hacks might work temporarily or on certain machine configurations, but the contents of eclipse.ini are not trivial nor arbitrary.
For the authoritative reference, see this [wiki page]:https://wiki.eclipse.org/Eclipse.ini#Specifying_the_JVM that explains the contents of the file. Also note the See Also links at the bottom of that page for more details about things like heap size, etc.
DO NOT delete eclipse.ini, EVER. It is also inadvisable to remove the -vm or Xmx options. If you do, you're asking for trouble.
Here are references from the wiki page pertaining to your problem:
This worked for me:
I closed all the other memory intensive applications on my Windows 7 machine. And I tried to open Eclipse, and, voila, it worked.
Some time it's not your eclipse.ini; it's your JDK which is crashed. You can check it by writing following command in a command prompt:
c:\> java -version
If this command shows the following error:
Error occurred during initialization of VM
java/lang/NoClassDefFoundError: java/lang/Object
Then first uninstall JDK and reinstall it.
Eclipse will be in action again ;) As today I have got the same problem, and
the above is suggested by Itachi Uchiha.
Faced the issue when my Eclipse proton could not start.
Got error "Failed to create the Java virtual machine"
Added below to the eclipse.ini file
-vm
C:\Program Files\Java\jdk-10.0.1\bin\javaw.exe
You need to add javaw.exe full path with forward slash i.e. / instead \ to eclipse.ini even you are on Windows. Like below:
-vm
C:/Program Files/Java/jdk-14/bin/javaw.exe
Also the above lines must be placed before -vmargs.
Adding this fixed the issue for me:
-vm
D:\Java\jdk1.6.0_29\bin\javaw.exe
Reduce param size upto -256

i had that following issue. so i did was find that eclipse.ini file in the eclipse installation folder.
then i edited as follows
add java jdk file desitination for -vm.remove XX things and add XX:MaxPermSeze=256
For me it solved by changing the JDK bin path in the Path environment variable. Put the JDK bin path which has jre/bin/client/jvm.dll under JDK home.
STEPS TO SOLVE THE ISSUE :-
Open the eclipse.ini file from your eclipse folder.
It has some of add on configuration . Find the line –launcher.XXMaxPermSize.It will be the last line in this file. Now remove/delete the the default value 256m and save it.
-vm D:\Java\jdk1.6.0_29\bin\javaw.exe
I was facing the same problem, and I found the solution. There are issues in allocation of MaxPermSize. If you try to allocate more than your machine's free space then it gives this error in my issue. So try to reduce MaxPermSize.
I think it will help you to sort out your issue.

Also I use vmwarevfabric server 2.9 (incluided in sts)
can someone help me?
Assuming it's Eclipse/STS giving the error, try putting
-Xss4m
to the end of the file (or at least after -vmargs).
See How to increase the Java stack size? for more.
Being tracked by https://jira.spring.io/browse/STS-3578
Answer from there:
Workaround: find the tc server launhc configuration via the "Run >> Run Configurations ..." menu. Change the vm commandline option to increase the stacksize. I.e something like:
-Xss256k
So lately I'm having a problem while working in my apps inside eclipse the next message shows up while working with xml files:
ERROR: 'Java heap space'
I have read an try increasing inside the eclipse.ini file the:
-vmargs
-Xmx40m
-Xmx512m
to:
-vmargs
-Xmx512m
-Xmx1024m
but it will work for a while than after and hour or so it will give me the same error, I'm working in a MacBook air with 4gb ram.
I have
Eclipse SDK

Try this
In Run->Run Configuration find the Name of the class you have been running, select it, click the Arguments tab then add:
-Xms512M -Xmx1524M
to the VM Arguments section
Few useful links
What are the best JVM settings for Eclipse?

Edit:
Your eclipse.ini settings will take effect only if you change following:
Run -> External Tools -> External Tool

Run in same JRE in workspace.

Not sure what i is the issue?
If you have m2e or other Maven plugin installed, you should check if the option at 'Window -> Preferences -> Maven -> Download repository updates index on startup' is enabled. Disable it and see if it resolves out of memory issue.
If you are using eclipse or myeclipse, you can increase memory by making changes in .ini file (myeclipse.ini)
-Xmx2048m
-XX:MaxPermSize=1024m
-XX:ReservedCodeCacheSize=512m
-Dosgi.nls.warnings=ignore
It will solve problem connected with heap space.
Assuming this is a heap space problem, try this FAQ:
Eclipse-Wiki: FAQ How do I increase the heap size available to Eclipse?
This may not be directly related to the question, but this fixed the java heap issues I had:
Launch eclipse using eclipse -vmargs -Xmx2048m.
From the readme included with the eclipse install:
By default, Eclipse will allocate up to 512 megabytes of Java heap
memory. This should be ample for all typical development tasks.
However, depending on the JRE that you are running, the number of
additional plug-ins you are using, and the number of files you will be
working with, you could conceivably have to increase this amount.
Eclipse allows you to pass arguments directly to the Java VM using the
-vmargs command line argument, which must follow all other Eclipse specific arguments. Thus, to increase the available heap memory, you
would typically use:
eclipse -vmargs -Xmx<memory size>
with the value set to greater than "512M" (512 megabytes
-- the default).
Old question, but I got this issue and adding more memory did not solve, so I rebuilt the java index by applying this comment from eclipse bug tracker:
I Quote:
Click in "Quick Access", Type "Rebuild Java Index" (Actually just start typing it, use the auto completion), Hit enter.
From yesterday I receive the message: "Failed to create the java virtual machine" in all Java applications in my Windows machine. Maybe I had a virus or something similar. The only advice I found on other sites is to set the heap size to a lower value. The problem is that I have big applications running that requires at least 1024M heap size. Also my machine has 4GB Ram so I think that it isn't a too low memory problem.
Carefully move the current JDK / JRE installation to one side, and install a fresh copy. If it works, you are done. If not, you have eliminated the possibility that this is a corrupted installation.
Another possibility is that this is really a path problem. Can you run java -version from a command prompt? Can you compile and run a Java "hello world" program from the command line?
Yes, in theory it could have had a virus ... or someone could have tinkered with the installation.
There are a few sites listing that error that differentiate between the heap and perm space. If you're running this through eclipse, try removing the default perm space value in the eclipse.ini:
--launcher.XXMaxPermSize
256m
Sun JVM needs contigous memory block. In windows this could a problem due to dll-rebasing. http://www.drdobbs.com/184416272;jsessionid=HJJRNPUURRDIZQE1GHPCKHWATMY32JVN
Is there any thing else changed?
We got similar problem we installed some new applications(guess it was Citrix) on it. A tool we used was from here http://www.codeproject.com/KB/DLL/RebaseDLLs.aspx (download the code and modify)
If it is left to you, then consider moving to 64bit jvm.
Same problem even i was facing when i first started eclipse..
Just change the value of "–launcher.XXMaxPermSize" in eclipse.ini file..
The eclipse.ini file should now look like this:
-startup
plugins/org.eclipse.equinox.launcher_1.1.0.v20100507.jar
–launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.0.v20100503
-product
org.eclipse.epp.package.jee.product
–launcher.defaultAction

–launcher.XXMaxPermSize
256m
–launcher.defaultAction
openFile
-vmargs
-Dosgi.requiredJavaVersion=1.5
-Xms40m
-Xmx512m
Did you try to reinstall Java? Maybe also update to latest version.
It is because Eclipse cannot find the path of javaw.exe
Just edit "eclipse.ini" file, adding this path:
Open the file and attach following sentences (replacing with your own path if different):
-vm
C:\Program Files\Java\jdk1.7.0_03\bin\javaw.exe
Sample:
-startup
plugins/org.eclipse.equinox.launcher_1.1.0.v20100507.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.1.R36x_v20100810
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256m
--launcher.defaultAction
openFile
-vm
C:\Program Files\Java\jdk1.7.0_03\bin\javaw.exe
-vmargs
-Xms40m
-Xmx384m
Changing the before file into:
"-vm C:\Program Files\Java\jdk1.7.0_03\bin\javaw.exe"
solves the problem mentioned earlier
First I had tried to make changes in eclipse.ini file as there was told here, but that did not help.
I simply deleted this .ini file, it helped and Eclipse launched.
