Hi,

I really hope someone can help me with this..
I'm trying to execute a JUnit launcher and I keep getting:

Error occurred during initialization of VM
Could not reserve enough space for object heap

I've tried everything from low and high values on each variable:
-Xms
-Xmx
-XX:PermSize
-XX:MaxPermSize

both on eclipse.ini and on the launcher VM parameters.
I'm running out of options.
Does anyone have any idea on what might be the problem?

Important note: What I'm trying to execute is not really a junit, but a cucumber feature with the cucumber eclipse plugin cukes.info/cucumber-eclipse.

help please... Sad

Andre,

The -Xmx option controls that. If you have a 32 bit JVM you have to be
careful not to make it larger than the largest possible heap possible on
the 32 bit JVM. Significantly larger than -Xmx1g is likely to cause
problems.

Thanks Ed,

I'm aware of that. My problem was not knowing where those values were actually configured.
I only knew the eclipse.ini file and the launcher vm parameters, but there is another place where these values can be configured. The eclipse JRE configuration has an option named default VM parameters. The invalid values where configured there.
Problem solved.

Thanks Ed.
