How to solve the JVM creation failed error when starting Netbeans

Submitted by Massimiliano on 04/07/2011

For those working with NetBeans on a Windows ( for sure XP and Vista ) machine this error is well known.

Do not worry, fix is very simple, just add an extra option in the configuration file.

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"

Restart NetBeans and enjoy coding.
