Sandeep More updated KNOX-900:
------------------------------
Attachment: KNOX-900.001.patch
In this particular UnitTest we open 100 websocket sessions and try to send data
through them. For some reason, intermittently some sessions seem to die, the
fix tries to look for closed and null sessions before sending data.
> UnitTest WebsocketMultipleConnectionTest intermittantly fails with NPE
