after upgrading to eclipse Juno, Jboss now starts with a set of JAVA_OPTS that are so low that I get an Out of Memory error, PermGen sp, when doing almost anything with the server.

Changing settings in my Shell definition of JAVA_OPTS,  Jboss' run.sh and run.conf files, or the eclipse runtime ini file have no effect on the reported JVM memory sizes shown when the server starts.

I have done a fair amount of googling,  which suggests things i have already tried,  and doing a find/grep on my file system looking for the offending memory setting.  no joy.
It seems to me (newbie that i am) that the gizmo called "JBossTools is launching my instance of the JBoss server inside of eclipse,  but i have had no luck tracking down where or how this element starts. (see console output below)

any hints on this one would be greatly appreciated.
