----------------------------------

             Summary: Transactions committed immediately before cache stop can block shutdown
                 Key: ISPN-6671
                 URL: https://issues.jboss.org/browse/ISPN-6671
             Project: Infinispan
          Issue Type: Bug
          Components: Core, Test Suite - Core
    Affects Versions: 7.2.1.Final, 8.0.0.Alpha1
            Reporter: Brad Maxwell
            Assignee: Dan Berindei
            Priority: Blocker
             Fix For: 8.2.1.Final, 9.0.0.Alpha1, 8.1.4.Final


This is causing random failures in {{DistributedEntryRetrieverTxTest.verifyNodeLeavesBeforeGettingData}}.

The test inserts some values into the cache, starts an iteration, and then kills one of the nodes. In rare instances, the killed cache only receives the TxCompletionCommand for one of the writes after it started the shutdown, and ignores it. That leaves the remote tx on-going, and {{TransactionTable.shutDownGracefully()}} blocks for 30 seconds - causing a {{TimeoutException}} elsewhere in the test.
