I've been using eclipse 5.5.1, but I recently went to a new machine and I've been asked to go to MyEclipse 10.5.  Code that was running fine in 5.5.1 is now getting a java heap space error in 10.5.  The 10.5 eclipse.ini file has:

#utf8 (do not remove)
#utf8 (do not remove)
-startup
../Common/plugins/org.eclipse.equinox.launcher_1.2.0.v20110502.jar
--launcher.library
../Common/plugins/org.eclipse.equinox.launcher.i18n.win32.win32.x86_64_4.2.0.v201201111650
-install
C:\Java\MyEclipse10.5\MyEclipse 10
-vm
C:\Java\MyEclipse10.5\Common\binary\com.sun.java.jdk.win32.x86_64_1.6.0.013\bin\javaw.exe
-configuration
C:\Java\MyEclipse10.5\MyEclipse 10\configuration
-vmargs
-Xmx512m
-XX:MaxPermSize=256m
-XX:ReservedCodeCacheSize=64m
-Dosgi.nls.warnings=ignore

So I decided to bump up some of the numbers:

-Xms1024m
-Xmx2048m

But I still get the java heap space.  And I've tried upping the MaxPermSize and ReservedCodeCacheSize and those do not fix anything.

When I remove the sql driver file from the jboss lib directory, I no longer get the java heap space error, but of course then I get a different error because it does not find any driver file.

So any ideas for this?

I'm using jboss 4.0.4 and jdk 1.5.0.17.
