Here's the tomcat output of from 'eclipse -consolelog':

That output is the same as what gets spit out on a working FC-6 so that won't
help with this problem.

I tested help with Sun's VM and it's working so this is a GCJ problem. I'll work
on narrowing down a test case.
Comment 3 Ben Konrath 2007-04-26 00:45:10 EDT
Tom / Andrew / Gary,

Just thought I'd let you know that this is in the pipes. I'll let you know when
I've narrowed it down a little.
Comment 4 Andrew Haley 2007-04-26 06:02:57 EDT
You say here that "output is the same as what gets spit out on a working FC-6".

I take it, then, that this bug is not an F7 regression, and has been around for
some considerable time.  Is this correct?
Comment 5 Ben Konrath 2007-04-26 11:46:39 EDT
Sorry, I wasn't clear there. What I meant to say was that text output from
-consolelog is the same as FC-6 so that doesn't help debug the problem. This is
in fact a Fedora 7 regression.
Comment 6 Andrew Haley 2007-04-26 12:10:45 EDT
OK, I'm looking now.
Comment 7 Andrew Haley 2007-05-02 11:50:16 EDT
This is because Eclipse needs MX4J.  Try this fix:

sudo ln -sf /usr/share/java/mx4j/mx4j.jar  /usr/share/java/gcj-endorsed
Comment 8 Ben Konrath 2007-05-03 01:14:57 EDT
That fixes the problem, thanks!
Comment 9 Gary Benson 2007-05-03 04:14:12 EDT
In what sense does it need it?  Does it specifically require MX4J features, or
does it just not work with libgcj's javax.management?
Comment 10 Gary Benson 2007-05-03 04:21:46 EDT
Oops, never mind, I just saw
Comment 11 Andrew Haley 2007-05-03 13:22:51 EDT
