Subject [jira] [Created] (FLINK-5642) queryable state: race condition with HeadListState
Date Wed, 25 Jan 2017 13:32:26 GMT
Nico Kruber created FLINK-5642:

             Summary: queryable state: race condition with HeadListState
                 Key: FLINK-5642
                 URL: https://issues.apache.org/jira/browse/FLINK-5642
             Project: Flink
          Issue Type: Bug
          Components: Queryable State
    Affects Versions: 1.2.0
            Reporter: Nico Kruber
            Assignee: Nico Kruber

If queryable state accesses a HeapListState instance that is being modified during the value's
serialisation, it may crash, e.g. with a NullPointerException during the serialisation or
with an EOFException during de-serialisation.
