Istvan Toth commented on PHOENIX-5937:
--------------------------------------
Thank you for digging into this, and the fix.
1. Nit: The indentation seems to be off
2. Not using Java 8 features would make backporting to 4.x easier, and the code
more consistent
3. You have dug into the code deeply, and you added the specific circumstances
that triggered the bug for me as a new else if branch.
I do not understand the whole context of this change. Could you explain how did
you come to the conclusion that this is indeed the only case where this bug
triggers ?
