I just upgraded form Java 1.7.51 to Java 8 and Eclipse stopped running. I made the changes and explicitly declared the VM (as you can see in the image). It started with an error that VM (2048MB) could not be allocated so I removed the XMX setting.
Is there something I missed? What have I done wrong?
It looks like you're trying to run the 64-bit version of Eclipse ("...launcher.win32.win32.x86_64") with a 32-bit JVM (It's in "Program Files (x86)"). Check to make sure you've installed the 64-bit version of Java 8.

I'm having a very odd issue with Java exiting abruptly and randomly.
I have a Macbook with M1 system (2021 model), with 32GB RAM. I'm running a Windows 11 (ARM64 Insider Preview) VM with Parallels. I have 16GB of RAM allocated for the VM, and 6 cores. I have Liberica JDK 8 (full with JavaFX) installed both on the host and the VM. I'm developing a multi-module Maven project, same project on both the host side and the VM side (the project depends on some Windows side things for some tasks, which is the reason I'm running the Windows VM on the side).
Output from java -version:
openjdk version "1.8.0_332"
OpenJDK Runtime Environment (build 1.8.0_332-b09)
OpenJDK 64-Bit Server VM (build 25.332-b09, mixed mode)
I've also tried with Azul JDK and had the same issue with it.
On the host side everything works as it should. Maven and Java commands both run successfully with no interruption or issues. On the Windows VM side however, it seems that Java just randomly exits with no error logs or anything really. I noticed it just hangs for a few seconds, and then just exits abruptly. I noticed that it may happen while running a Maven command, or for example running a .jar package with java -jar. Here's a picture of what it looks like (same happens on the picture above though):
A couple weeks back I had no issues at all. But then I had to reinstall Parallels and the VM (reinstalled the whole W11 OS), and suddenly these issues started occurring. I've tried adding -XX:+HeapDumpOnOutOfMemoryError to MAVEN_OPTS environment variable to see if it's a OutOfMemoryError, but it did not seem to have any results.
Any ideas?
In case anyone runs into this issue: I was able to resolve this issue by installing the Windows 11 VM into Parallels from an image downloaded from UUP Dump.
I tried reinstalling the VM downloaded from the Microsoft's Insider Preview page, but the issue still persisted and nothing seemed to be able to fix it. Java still exited randomly pretty frequently.
I downloaded the latest Windows 11 image from UUP Dump and installed that one instead. Installed the exact same versions of Maven, Java, Groovy etc. and surprisingly, the issue vanished. I've been able to run Java on my VM for a day now without issues, whereas with the image downloaded from Microsoft I was able to reproduce the issue pretty much within minutes after configuring my environment and cloning the Git repo of the project I'm developing.
A lot improved for me after switching to ARM64 Java (Microsoft's was first one I found, there may be others).
Some background: not sure if I had exactly the same issue, but vscode compiling and code checking was slow and unreliable, and my Mendix Java application kept crashing or not even starting. Since that uses Java 11, that's what I installed the ARM64 version of. This is in Windows 11 ARM, from Microsoft's Preview page, updated (hang the first try, but worked the second).
I have a very old application (published in 2001) I am trying to get working in Windows 7/8/10. There is a setup.exe part of it that is using Java in some capacity, and not working correctly. I suspect it is using java because I decompiled the JAR file packaged with the application and there are references to several setup steps within the .java files (along with a file named setup.java). There is also a jre folder published with the application as well, running the following (dated) version:
F:\jre\bin>java -version
java version "1.3.0_01"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0_01)
Java HotSpot(TM) Client VM (build 1.3.0_01, mixed mode)
At first I suspected the application was using the systems environmental variables to use the currently installed version of JAVA, but I ruled that out by completely purging JAVA from the system and retesting - same results.
I next tried to simply update the folder to the latest version. As expected however, there were calls being made that were no longer supported (error message was referencing _JVM_IsVMGeneratedMethodl).
At this point I am running out of options. I could always run this application in a VM (and it works fine), but I would prefer to somehow package it in a nice streamlined way for easy distribution and install. Is there anything I can do? I was thinking something along the lines of application virtualization but still reading up on it.
It's hard to tell without "being there", but I'm guessing that the old (1.3) JVM just isn't compatible with the more modern versions of Windows.
Your best bet is probably running it against whatever version of Windows the app was originally developed on, in a VM.
If you have / can get the complete source code, you could try recompiling it with the version of Java supported on your current system. But it's probably a long-shot.
If it is containing a JRE folder, then you could skip the installer and add some batch file to launch that .jar with the specific JRE via a command of this form:
java -jar pathToYourJAR
btw, you could also consider options to convert to executable, some older are mentioned here:
How can I convert my Java program to an .exe file?
some of them may allow you to select which JRE to bundle/use
I'm working on a bluetooth java application under eclipse in OS X 10.10.1 Yosemite 64bit with the blue cove-2.1.0 jar. When I run the application I get the error message:
Native Library bluecove not available
Through a web search I found that the issue is caused by the 64 bit version of Java, but when I try to run the application with the -d32 argument passed to the VM I get the error:
Error: This Java instance does not support a 32-bit JVM.
Please install the desired version.
Is there anyway to run this application despite the 64 bit configuration? or is there any other library despite bluecove that can manage a 64 bit environment?
A similar thing happened to me with a different java application (jruby), around which I was able to work by resetting my JAVA_HOME to a JVM that supports 32-bit mode. Essentially your 64-bit JVM is trying to tell you that it won't run in 32-bit mode, even when you specify the -d32 option.
To work around this, try running: /usr/libexec/java_home -d32
On my 64-bit Yosemite machine, that command returned /Library/Java/JavaVirtualMachines/1.6.0_65-b14-462.jdk/Contents/Home, which is the path to a JVM on my machine that will run in 32-bit mode. If you have one or more 32-bit-capable JVMs on your machine, you'll get a path to one of them, which you can then use to set your JAVA_HOME variable accordingly and you'll be off to the races.
If you don't have a 32-bit-capabile JVM on your machine, you will need to install one via the Oracle web site or homebrew and then set your JAVA_HOME accordingly.
If you want to skip a step or two, just do this -- export JAVA_HOME=`/usr/libexec/java_home -d32` -- which will automatically set your JAVA_HOME to the first detected instance of a JVM capable of running in 32-bit mode.
I got the following warnings, but don't understand why. It appears I have Java 7U71.
LNGRDUM-4157808:bin xyx$ ./cassandra -f
Cassandra 2.0 and later require Java 7u25 or later.
LNGRDUM-4157808:bin xyz$ java -version
java version "1.7.0_71"
Java(TM) SE Runtime Environment (build 1.7.0_71-b14)
Java HotSpot(TM) 64-Bit Server VM (build 24.71-b01, mixed mode)
What I don't know is why it says you need to upgrade, even though it appears that your Java version is up to date. What I do know is that I had a similar issue recently, and I resolved it this way:
Install the latest JRE from https://www.java.com/en/download. This will install the latest version of Java, but it will NOT update the default "java" used by Terminal/bash, and so Cassandra won't pick it up.
To make Cassandra and Terminal use the newest version, add the latest install to your $PATH. This is complicated for a few reasons. First, it's not obvious where Java installs itself, and it ISN'T to the default /user/bin/java location. It turns out that it's in /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin. Second, there's a space in the directory, so you have to be careful about that.
Theoretically, it should be possible to edit your $PATH by editing /etc/paths. However, I was not able to get this to work (maybe something to do with the space in the directory?). Instead, I ended up editing my $PATH a different way, as shown here. The line in my .bash_profile looks like this:
export PATH="/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin":$PATH
If you have any trouble doing this, just let me know.
Test that you've done this properly by opening a new Terminal (this is important as it will reload your .bash_profile), then typing java -version. Hopefully this now displays an even newer version than before. You can double-check that java is being sourced from the right place, and you've successfully modified your $PATH, by typing which java.
Doing that fixed my Cassandra. Hopefully it will fix yours, too.
You must have multiple Java versions installed. Check your PATH setting and change it to point to the correct version:
LNGRDUM-4157808:bin xyx$ SET
. . .
PATH=<bunch of stuff>:/Library/Java/JavaVirtualMachines/jdk1.7.0_71.jdk/Contents/Home/bin
If JAVA_HOME is set (doesn't need to be for running Cassandra), make sure it isn't pointing to a different Java installation.
I am working on java wicket framework and Apache tomcat. When I tried to start tomcat, it shows Java Virtual Machine Launcher pop window "Could not create the Java Virtual Machine".
After clicking on "OK" button on Pop window, it shows the error on console.
Error occurred during initialization of VM.
Could not reserve enough space for object heap.
Please give me any reference or suggestions.
Error:

java version "1.8.0_101"
Java(TM) SE Runtime Environment (build 1.8.0_101-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.101-b13, mixed mode)
I was also facing this issue when we upgraded from java 8 to java 10. I solved by removing
-Djava.endorsed.dirs="C:\Program Files\Apache Software Foundation\Tomcat 8.5\endorsed"
from the argument.
Press Windows+Pause keys simultaneously to open the "System" window. You can alternatively open the control panel manual to go there if you prefer it that way.
Click on "Advanced system settings" on the left then click "Advanced" tab.
Select environmental variables here.
Click on new under System Variables.
Enter '_JAVA_OPTIONS' as the variable name.
Enter '-Xmx1024M' as the variable value.
Click ok twice.
Edit your Catlina.bat so that your -Xmx settings are less than your physical memory
See Tomcat 7: How to set initial heap size correctly?
I was facing the same issue while I was using "jdk-10.0.1_windows-x64_bin" and eclipse-jee-oxygen-3a-win32-x86_64 on Windows 64 bit Operating System.
I resolved this issue by changing my jdk to "jdk-8u172-windows-x64". Now it's working fine.
Add the system variable _JAVA_OPTIONS and in the "new variable value" add "-Xmx1024M".
Xmx sets the maximum heap memory size
The error does not say much and lot of things can be wrong. One thing that was wrong in my case was following
-x.DargName=108352123
Which is clearly wrong and should have been
-Dx.argName=108352123
For me it was picking the default JVM v6 set in env vars.
Needed to explicitly add below in eclipse.ini to use v8 which is req by photon.
-vm
C:\Program Files\Java\jdk1.8.0_75\bin\javaw.exe
--launcher.appendVmargs
-vmargs
-Dosgi.requiredJavaVersion=1.8
NOTE : Add the entry of vm above the vm args else it will not work!
You just need to add JAVA_HOME to your environment variable. Just point this variable to jdk location(not the jdk bin location) as shown in the below image.
I was facing the same issue while I was using JDK 1.8.0_05 64 bit and eclipse-jee-oxygen-3a-win32-x86_64 on Windows 64 bit Operating System.
I resolved the issue by changing JDK version jdk1.8.0_05 to jdk1.8.0_172
On ubuntu (version 18), some application support java 8 and do not support java 11.
If this is the case , you can switch to java 8 by following instruction on below topic :
https://askubuntu.com/questions/1133216/downgrading-java-11-to-java-8
I had to add an older jdk on my project.
Right button on Project folder > Properties > Java Build Path > Libraries > Add Library > JRE System Library
In case you don't have the package for jdk8, download the jdk that some user mentioned above (http://download.oracle.com/otn-pub/java/jdk/8u172-b11/a58eab1ec242421181065cdc37240b08/jdk-8u172-windows-x64.exe) and click on "Installed JREs" and search for the directory you downloaded the jdk8.
Then click on Finish.
Remove the apache server and add again.
The magic is done ;)
I had the same issue today when running the ancient software Dundjinni, a mapping tool, on Windows 10. (Dundjinni requires a rather old installation of Java; I haven’t tried updating Java, for fear the programme will fail.) My method was to simply run Dundjinni in administrator mode. Here is how:
Click Start or press the Start key, navigate down to the software, rightclick the programme, choose More, then choose Run as administrator. Note that this option is not available if you simply type the name of the software.
I was facing the same issue when I was using tomcat 8.5 with Java 10. I installed Java 8(1.8.0_171) and it's working fine without any issues.
If none of the other options works, then this could be an issue with the version of the JDK itself, just uninstall the current jdk and install the latest version.
I also faced this issue. After trying everything, I upgraded to the latest JDK and this issue was resolved on its own.
