Sounds like it could relate to #10816 (just a guess)

TatuLund · 2018-05-01T07:12:54Z

@tstsogoo What @knoobie suggest, could be right. You probably then should have some other exceptions on your log. The one you have here is the consequence, i.e. getSession throws this, because session creation had failed earlier. It is easy to verify the theory by testing 8.5-SNAPSHOT, which already has a fix. 8.4.1 is to be released ASAP as well.

tsuoanttila · 2018-05-04T14:03:44Z

@tstsogoo, can you test your issue with the just released 8.4.1?

tstsogoo · 2018-05-07T02:07:50Z

fixed by 8.4.1 @tsuoanttila
