Michael Bien closed NETBEANS-1115.
----------------------------------
Fix Version/s: ?
Resolution: Fixed
this got likely fixed at some point by a javac update or by other means - at
least I don't remember seeing this particular exception.
If this is still happening, please open a new issue on github and post a fresh
stack trace there (and the reproducer too). Thanks.

> }
> private void sayHello(String name) {
> System.out.println("hello " + name);

> After the first rename from sayHello to sayBye there is an editor hint on the

> cannot find symbol
> symbol: method sayBye(String)
> location: class FailingRenameWithNbJavac
> ----
> (Alt-Enter shows hints)
>
> After the second attempt, renaming sayBye to sayWhat in the unsaved file I

> As a side note, error message ("Cannot perform instant rename here") in the
> status bar just flashes by so one has to hold Ctrl-R in order to be able to
