ASF GitHub Bot commented on CURATOR-299:
----------------------------------------

GitHub user Randgalt opened a pull request:

    https://github.com/apache/curator/pull/145

    [CURATOR-299] WatcherRemovalManager must be updated when there's an exception, retry,
etc.

    If there's an exeption, retries exceeded, etc., the watcher was still being stored in
WatcherRemovalManager thus causing it to be incorrectly removed. This fix removes the watch
from the WatcherRemovalmanager on exceptions, retries exceeded, etc.
