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). -- What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |NEW Ever Confirmed| |1 Last reconfirmed|0000-00-00 00:00:00 |2004-07-31 16:10:13 date| | http://gcc.gnu.org/bugzilla/show_bug.cgi?id=16839 ^ permalink raw reply [flat|nested] 6+ messages in thread

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. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=16839 ^ permalink raw reply [flat|nested] 6+ messages in thread
