"JVM creation failed" in netbeans 7.1

Question

I can launch the Netbeans IDE successfully. But, when I run the sample applications in the IDE, I always get the JVM creation failed message.

If I clean it, I can run it successfully, but only once. So, if I have to run an application, I have to rebuild it. Why?

I Googled for JVM creation failed , but only found the solution to fix the issue in launching the Netbeans itself.

Answer 1

You can find.netbeans.conf under.

C:\Program Files\NetBeans\etc

This is the original conf row.

netbeans_default_options="-J-client -J-Xss2m -J-Xms32m -J-XX:PermSize=32m -J-Dapple.laf.useScreenMenuBar=true -J-Dapple.awt.graphics.UseQuartz=true -J-Dsun.java2d.noddraw=true"

Simply add this extra parameter to the above row.

-J-XX:MaxPermSize=128m 

Finally the row looks like.

netbeans_default_options="-J-client -J-Xss2m -J-Xms32m -J-XX:PermSize=32m -J-XX:MaxPermSize=128m -J-Dapple.laf.useScreenMenuBar=true -J-Dapple.awt.graphics.UseQuartz=true -J-Dsun.java2d.noddraw=true"

Now restart you NetBeans...

Answer 2

This error shows if you have any other IDE like Visual Studio opened. Just closing the that application will solve that problem.
