Yonik Seeley commented on LUCENE-818:
-------------------------------------
If we aren't guaranteeing an exception be thrown after a close, why are we
bothering to put the exception in the method signature?
It's already apparent to everyone that using something after it's closed isn't
good, so we were just cleaning up the error messages and making it easier to
debug. People shouldn't have specific application logic for this exception...
it should be treated as a program error.
IMO, listing the exception encourages people to catch it, suggests that they
can depend on the exception being thrown, and also makes it more difficult to
remove it from certain methods in the future.

> If you call addDocument on IndexWriter after it's closed you'll hit a
> hard-to-explain NullPointerException (because the RAMDirectory was
> closed). Before 2.1, apparently you won't hit any exception and the
> IndexWrite will keep running but will have released it's write lock (I
> think).
> I plan to fix IndexWriter methods to throw an IllegalStateException if
> it has been closed.
