Can anyone make a test case for this? I was unable to reproduce it.

While importing 0.90 into libgcj I also noticed this. Setting this package to
bc (like the other awt peer implementations) gives:

------- Comment #4 from tromey at gcc dot gnu dot org 2006-03-11 01:40 -------
Mark's problem appears to be a bytecode generation bug.
We are generating:
6: invokespecial #65=<InterfaceMethod java.awt.peer.WindowPeer.setBounds
(int,int,int,int)void>
But this is incorrect as you cannot invoke an interface method
with invokespecial. And, super.foo() should never call an
interface method anyway.
I don't know whether or how the original report is related,
but it isn't unreasonable to assume that it is.

I added a main to the reduced test case:
public static void main(String[] args)
{
SwingFramePeer s = new SwingFramePeer();
s.setBounds();
}
With this I can almost reproduce the original bug:
opsy. gcj --main=pr26390 -o P pr26390.java
/tmp/cczetk2m.o(.text+0xd): In function `void
pr26390$SwingFramePeer::setBounds()':
pr26390.java: undefined reference to `void pr26390$WindowPeer::setBounds()'
I say "almost" since from the original report I would expect
the missing method to come from SwingWindowPeer.

------- Comment #7 from tromey at gcc dot gnu dot org 2006-03-13 19:07 -------
The bug here is that gcj implements method inheritance incorrectly.
In particular it does not consider SwingWindowPeer.setBounds
as a candidate method for the super.setBounds() call, because it
has no notion that there is a method named "SwingWindowPeer.setBounds".
Instead it only considers SwingComponentPeer.setBounds -- which is
not maximal and thus not selected.

I'm not an expert with Java but am trying to compile gcc 4_2 branch (CVS)
and I have the same problem as is described in this bug report. The fixes
mentioned in this report _seem_ to have been applied but am getting a 'similar'
error message:
Here is the part of the make where it fails:

I'll leave any 'fixing' to someone more expert at java (so I don't break gcc
somewhere else :( ). I tried changing to above to simply use system's gcj:
gcj -c -o gnu-java-awt-peer-swing.lo @gnu-java-awt-peer-swing.list
