Question

I am getting this error message when I start Eclipse Helios on Windows 7:

Failed to create the Java Virtual Machine

My eclipse.ini looks as follows:

-startup
plugins/org.eclipse.equinox.launcher_1.1.0.v20100507.jar
-vm
P:\Programs\jdk1.6\bin
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.0.v20100503
-product
org.eclipse.epp.package.jee.product
--launcher.defaultAction
openFile
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
512m
--launcher.defaultAction
openFile
-vmargs
-Dosgi.requiredJavaVersion=1.5
-Xms120m
-Xmn100m
-Xmx1024m

My JAVA_HOME is correctly set as far as I can tell. How can I fix this?

Things I have tried so far:

1. Adding the full path to javaw.exe
   -vm
P:\Programs\jdk1.6\bin\\bin\javaw.exe
2. Removing the -vm option altogether
3. Removing --launcher.XXMaxPermSize fixes the issue, but it causes permgen errors
4. Removing the value 512 of --launcher.XXMaxPermSize fixes the issue, but it causes permgen errors
5. Reducing -Xmx to 512m also fixes the issue.

Why can I not use ‘1024m’ for ‘-Xmx’ and ‘–launcher.XXMaxPermSize’?

Answer 1

Try removing the -vm P:\Programs\jdk1.6\bin lines.

Also, a general recommendation: set -Dosgi.requiredJavaVersion=1.6, not 1.5.
