Eclipse running out of memory, or..?

This is incorrect.  We build the bytecode exactly the same as upstream:
with the JDT Core compiler, ecj.  After the build is done - the exact
same as upstream - we natively-compile all of the jars with gcj to
shared libraries which can be used by gij.  But you said you were
running with the Sun VM so all you're using is the bytecode.
/usr/bin/eclipse is the binary (native) launcher just like upstream that
is used to spawn the VM.  In the case of Sun, at
least, the memory flags in the file I mention below should be respected.

You can fiddle with memory stuff (mx, etc.) in
/usr/share/eclipse/eclipse.ini.  It's the same as upstream except that
it's owned by root and managed by RPM instead of just an exploded
tarball :) .

You may get some more tips if you ask on fedora-devel-java-list as some
of the people there may have more experience with this kind of
situation.

One thing to confirm is that you are indeed running with the Sun VM.  If
you've downloaded plugins that aren't shipped with Fedora, they don't
contain the gcj-compiled bits and if you're just running with our stock
setup, they'll be purely interpreted by gij.  They'll run slower than if
there are .sos corresponding to the jars.  But if you're running with
the Sun VM then that's irrelevant.
