I don't have a small test case for this, but we've narrowed
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=151919 down to be a gcj
mis-compilation.  The jar that is being mis-compiled is
org.eclipse.ui.workbench.  The symptom is that files can't be opened in Eclipse.
 Removing the .jar.so makes the erroneous behaviour disappear.

The top of the stack trace (this appears in the Eclipse editor window where the
file contents should be) looks like this:

java.lang.ClassCastException:
org.eclipse.ui.internal.PlaceholderContributionItem cannot be cast to
org.eclipse.jface.action.ToolBarContributionItem
   at org.eclipse.ui.internal.EditorActionBars.getToolBarManager()
(/usr/lib/eclipse/plugins/org.eclipse.ui.workbench_3.1.0.jar.so)
   at
org.eclipse.ui.part.EditorActionBarContributor.init(org.eclipse.ui.IActionBars)
(/usr/lib/eclipse/plugins/org.eclipse.ui.workbench_3.1.0.jar.so)

I'll attach the bytecode of EditorActionBars but the entire jar is 2.4 MB so
it's probably stupid to attach the entire thing to this bug report.  I've put it
here instead:

http://people.redhat.com/overholt/org.eclipse.ui.workbench_3.1.0.jar

The source for this plugin is available here:

http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.ui.workbench/?only_with_tag=v20050331-2000

I'm sorry I can't be more specific.  I wanted to get this here while the
knowledge was fresh.
