failed to create java virtual machine error in springsource tool?

Question

I have downloaded springsource tool. But on install, it is giving me error "failed to create java virtual machine". Can anyone suggest me some solution?

This is my sts.ini

-startup plugins/org.eclipse.equinox.launcher_1.2.0.v20110502.jar

--launcher.library plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.100.v20110502

-product com.springsource.sts.ide

--launcher.defaultAction openFile

--launcher.XXMaxPermSize 384M -vm C:\Program Files\Java\jdk1.6.0\bin\javaw.exe -vmargs

-Dosgi.requiredJavaVersion=1.5

-Xmn128m -Xms256m

-Xmx768m

-Xss1m -XX:PermSize=128m -XX:MaxPermSize=384m

Answer 1

Find your sts.ini file usually in the root directory where you installed spring, try adding this as the first line in the file, make sure it points to YOUR JDK (You may need to change the path), also sometimes you need to put -vm and the path on different lines.

-vm C:\Program Files\Java\jdk1.6.0_20\bin\javaw.exe

My sts.ini

-vm
C:\Program Files\Java\jdk1.6.0_20\bin\javaw.exe
-startup
plugins/org.eclipse.equinox.launcher_1.1.0.v20100507.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.1.R36x_v20100810
-product
com.springsource.sts.ide
--launcher.defaultAction
openFile
--launcher.XXMaxPermSize
256M
-vmargs
-Dosgi.requiredJavaVersion=1.5
-Xms40m
-Xmx768m
-XX:MaxPermSize=256m

Answer 2

Today I had this problem with spring source tool and the resolution specified here worked better: Could not create the Java virtual machine

-Xmn128m
-Xms256m
-Xmx768m 
-Xss1m
-XX:PermSize=128m
-XX:MaxPermSize=384m

Reduced/changed max heap size to be same as MaxPermSize, and STS started without issues. -Xmx768m ---> -Xmx384m

Make sure your heap sizes are less than your RAM.
