Hello, when I launch the second eclipse, with a project that needs Xbase dependency, I get this error:

java.lang.OutOfMemoryError: PermGen space

¿Any solution?

Thank you very much.

Did you try increasing the PermGen space? (in the launch config).

Hi

I have modify the file eclipse.ini to increase it to 512:

-startup
plugins/org.eclipse.equinox.launcher_1.2.0.v20110502.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.gtk.linux.x86_1.1.100.v20110505
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
512m
--launcher.defaultAction
openFile
-vmargs
-Xms40m
-Xmx384m

is this what you meant???

Hi,

shouldnt you change the Jvm Arguments of your Launch Configuration (Run -> Run Configurations...) e.g. by adding
-XX:MaxPermSize=128m
there

Hi Christian

eclipse.ini editing is what Eclipse FAQs recommend; it fixes all uses of
one Eclipse.

I do the same as you which fixes one use of a potentially migrating Eclipse.

Hi Ed,

adding --launcher.XXMaxPermSize
256m

has no influence on runtime "eclipse applications" at least in my experience
the only influence is on "Launch Eclipse Runtime"

so you have
(a) always make sure you choose "Launch Eclipse Runtime" and not "Eclipse Application"
(b) add the XX:MaxPermSize manually to the Launch "Eclipse Application" Config

I've tried editing eclipse.ini at first, but didn't work. Changing the launch config did. Thanks Smile
