Following Eclipse code snippet that fails:
protected void join(InternalJob job) {
final IJobChangeListener listener;
synchronized (lock) {
listener = new JobChangeAdapter() {
public void done(IJobChangeEvent event) {
barrier.release();
}
};
job.addJobChangeListener(listener);
}
}
The error reports the line containing listener = as the problem.

Confirmed, reduced to:
class a1 { public int f(){return 1;} }
class t
{
Object f;
void g(a1 a) {}
void f()
{
final a1 a;
a = new a1 () { public int f(){return 0;}};
g(a);
}
}

Related to bug 16839. The problem might be the same problem after all because final are collected for
anonymous inner classes.

Yes, the underlying problem is the same as with bug 16839.
gcj captures all 'final' local variables in an anonymous class.
This is incorrect -- it should only capture those which are actually
used.

------- Comment #5 from tromey at gcc dot gnu dot org 2007-01-09 20:46 -------
All gcj front end bugs have been fixed by the gcj-eclipse branch merge.
I'm mass-closing the affected PRs.
If you believe one of these was closed in error, please reopen it
with a note explaining why.
Thanks.
