Ok it seems to happen only on first series of index updates, and only if no query was ever run before.

I'm actually having this fail with fs directory as well: same stacktrace.
Just that functionality is not affected in this case, as it kills the thread in the executor after having applied the work on the index. And the killed thread is then replaced by the Executor.
Fixed
