Subject Re: Processing-Time Timers and Checkpoint State
Date Mon, 09 Jan 2017 15:03:38 GMT
I just verified that this does indeed work on master and the Flink 1.2
branch. I'm also pushing a test that verifies this.

Stephan is right that this doesn't work on Flink 1.1? Is that critical for
you, if yes, then we should think about pushing out another Flink 1.x
bugfix release.

Cheers,
Aljoscha
