   > There is an integration test failure that seems related:

   > java.lang.IllegalArgumentException

   Yes, it is related.  However, the failure actually is an existing bug.   IncrementalChunkBuffer did not override equals(..) so that it uses Object.equals(..).  The failure shows that the released object is different from the removed object.  Will file a JIRA.
