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)
C:\Java\MyEclipse10.5\MyEclipse 10
C:\Java\MyEclipse10.5\MyEclipse 10\configuration

So I decided to bump up some of the numbers:


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
