---------------------------------
Resolution: Fixed
Hi,
We just merged 2 in the master fixes for the following issues.
https://issues.apache.org/jira/browse/FLINK-7835

I believe that these also fix the issue in this JIRA, this is why I am closing
it.
Please try the master, and if the problem persists, feel free to re-open it.
