This can be caused by a number of problems and since you didn't
post the code in question it is hard to say what is at fault.
Try and isolate the fault by compiling with the Jikes compiler
or with the same version of javac on a different platform as
suggested by others in this thread.
If the problem doesn't manifest itself on the alternative compiler
you have probably spotted a compiler bug. You will then have to
produce a small test case demonstrating the problem and submit it
to the compiler maintainers.
It is not unlikely that your problem is caused by a compiler bug.
Most compiler bugs I have seen manifest themselves when you use
inner classes or static{} initilizers but Javasoft doesn't really
have a track record of producing reliable code so I'd expect
anything. (To be fair, Jikes 1.13 has some analysis bugs as well.)

That is to be expected.

That is rather ugly.

You will have to try and pinpoint the problem or provide source
code for us to analyze. Without more details we can only speculate.
Cheers,
