This valid java code generates a compile error.

public class finaltest {
    public void main(String args[]) {
        System.out.println("got to main");
        switch(23) {
        case 1:
            final String s = "x";
            break;
        case 2:
            new Runnable() {
                public void run() {
                    System.out.println("run");
                }
            };
            break;
        }
    }
}

I believe the bug here is that gcj captures all
final local variables in an anonymous class constructor,
whether or not those variables are used by the class.
This means that "s" appears to be used by the 
"new" invocation, causing the definite assignment code
to emit an error (which would be correct if the anonymous
class actually had a use of the variable).

This email makes absolutely no sense.  What information is this message 
trying to tell me?  Does anyone even know the difference between information 
and data anymore?

Nothing, I was adding a keyword so we can keep track of different kinds of bugs.
Also I was reconfirming the bug so we know that it is still a bug in the latested CVS version of gcj.

------- Comment #4 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.
