Chetan Mehrotra commented on OAK-3595:
--------------------------------------
[~tmueller] Most likely the issue here is that in LucenePropertyIndex while
plans are being calculated an exception is thrown and that causes the query to
fail and thus eventually causing the repository to fail to register.
Now not sure on the right way to fix it - Currently its fail fast. One way can
be that QueryEngine catches any exception while getting plans from Index
providers and ignore any index if there is an error. Or we fix
LucenePropertyIndex to catch any exception and then ignore plan for that index.
