Any ideas what is making this an error instead of a warning or ignore?

Eric,
Are you sure? I think an @Override that's not really an @Override must
be treated as an error and there is no way to turn that off. Is it
possible that the other guy is using Java 6.0 and you're using Java
5.0. I believe (but I'm not sure) that in 6.0 that @Override can also
be used to indicate that you implement a method in an interface even
when you don't actually override a method declaration in another class...

That could very well be the case - I am definitely set up to JDK 1.5 and
at least some of my coworkers are running Eclipse under 1.6 so their
default is likely 1.6. I'll test out that theory next week.
Thanks,
Eric

Thanks for this hint. This is exactly the same problem, we had here. But
I am running Eclipse with Java 1.6, but I use 1.5 for my projects. My
compiler compliance level is also set to 5.0.
Now if I set the cleanup properties to add missing "@Overrides", it adds
the also to implemented interface methodes, that does not work with 1.5.
Is it a bug or a feature?
Greets,
Adam

You should enter a bug for that, since Java 5 projects will immediately
mark such annotations as an error. Clean-up should not produce compile
errors, obviously.
