Felix Wollschläger commented on FLINK-11774:
--------------------------------------------
I encountered the same exception when using a custom type as a key. It seems
like it only occurs when restoring from a savepoint or checkpoint.
I already encountered it back with Flink 1.3.2 (so it doesn't seem to be a new
bug) and kept the stacktrace. If it helps, this was the stacktrace in Flink
1.3.2:
{code:java}

Back then I simply changed my key to a String but it would be nice if this
would be fixed for future versions.
