Hello, Sorry for the delay. The bug is not in Gelly, but is, as hinted in the exception and as can be seen in the logs, in Flink's Runtime. Mihail may actually be on to something. The bug is actually very similar to the one described in FLINK-1916.
However, as can be seen in the discussion thread there, it's a bit difficult to fix it without some steps to reproduce. I unfortunately managed to reproduce it and have opened a Jira... FLINK-2360 <https://issues.apache.org/jira/browse/FLINK-2360>. It's a similar delta iteration setting. Hope we can get some help with this. Thanks!
