Logstash Load Error - java

When I try to run logstash, I get a load error: JRuby ext built for wrong Java version. Does anyone know what this means and how I can resolve it. I`m running this on putty if it makes a difference.
Command Line Error

I had this error on a Windows box, and I solved it by updating Java.
In my case, I updated it from an earlier version of Java 8 to Java version "1.8.0_121".

Alert: "Failed to create the Java Virtual Machine" [duplicate]

I have formatted my Mac due to some storage issues. Before this, I used Eclipse in a proper way. Now i have installed the JDK
Then, i have installed Java
Until now everything seems to be correct but when I open the Eclipse installer...
What can I do to fix this? I need to work with this the soon as possible.
Thanks
Eclipse on macOS will not start with Java 14 installed, this is being tracked in Eclipse bug 561273.
Installing Java 8 as well does not help. You need to remove the Java 14 install. You could use the Java 13.0.2 release instead.
Eclipse have determined that the root cause of this issue is a change in Java 14 which is described in this bug report JDK-8238225. The fix for this should be in Java 14.0.1
Update: Eclipse runs fine with Oracle Java 14.0.1 so the issue has been fixed.
I also asked this question which was closed, that's why I answer what I have found out: Eclipse will not install on Mac OS Catalina 10.15.4, saying the above error message
Failed to create the Java Virtual Machine.
Deinstalling jdk and install an older one wouldn't help on its own because Eclipse is refusing to install in the first place (as mentioned above). What I have done:
i´ve installed an JDK with boost (you can try several, mine worked with Version 13)
I edited the installer:
Download the dmg file
convert the dmg-file with "hdiutil convert /dev/disk3s1 -format UDRW -o devimage"
mount the converted dmg-file with: "hdiutil attach -owners on devimage.dmg -shadow"
Edit the /Volumes/Eclipse/Eclipse.app/Contents/Info.plist: there is a section which is commented and there you can try the jdk version. You have to give the full path to the java executable, for example:
<string>-vm</string><string>/Library/Java/JavaVirtualMachines/jdk-13.0.2.jdk/Contents/Home/bin/java</string>
Then my eclipse started from the (already) mounted Eclipse image without complaining
I had the same issue myself a while back. In your Eclipsepedia it provided an example of what the eclipse.ini file looks like when your trying to specify a JVM. So just change the eclipse.ini file and then make sure that you have all of the correct documents in that path to match the example.

Java Mac application failed with error code -10810

I'm making a Java application in Eclipse that needs to run on both Windows and Mac. I made it into a Mac app that I'm able to run independent of Eclipse on my laptop, but when I tried to run it through terminal on another Mac machine (that had the Java version that I required), it showed the error message:
Cannot run (/Users/agastya/Desktop/appname.app). Error Code: -10810. How can I resolve this issue?
Thanks!
try to run the application from terminal
please use the full path to appname.app
It appears to be that you need to set JAVA_HOME and PATH
Please see the answer here

Uninstalling/Installing JDK

For some reason the installation of the oracle JDK didn't work on the machine I am using. It was installed before I started using it so I figured I would uninstall it and install it properly. When I try to uninstall it in Windows I get the following error message:
Error 1316: A network error occurred while attempting to read from the file C:\Installer\jdk1.7.0_51.msi
This file doesn't exist on this machine, I think it was somehow deleted. Does anyone know how to get around this problem.
I recently experienced the same problem. I solved it using Microsoft Fix it tool.
I just launch it and it removes completly the JDK on my computer.

jdk1.6 update 32 and JavaFX2.1 does work?

i am trying to create a embedded browser using the JavaFX2.1 by using jdk1.6 update 32 however it looks like that all the programs are not working because of jdk1.6u32. but at the requirement its clearly mention that JavaFx2.1 will work with the jdk1.6update 32.
Does anybody knows what is the reason?
I am right now trying to run the sample programs which comes with javaFx2.1 and the below one
http://docs.oracle.com/javafx/2/swing/SimpleSwingBrowser.java.htm
while executing the above program with jkd1.6u32 and jdk1.7u4 program compiles and executes but doesn't display any page.
I saw the below error on the console:
Device "Mobile Intel(R) 4 Series Express Chipset Family" (\\.\DISPLAY1) initialization failed :
WARNING: bad driver version detected, device disabled. Please update your driver to at least version 6.14.10.5303
Its better you install the 1.7 update 4 version of java because in that the java fx 2.1 is bundled with may be that works for you.
i figured it out it was a problem with version mismatch between my java compiler and java runtime env.
