             Summary: MultiNodeTest#testQuorumOverride may fail sporadically
                 Key: QPID-7080
                 URL: https://issues.apache.org/jira/browse/QPID-7080
             Project: Qpid
          Issue Type: Bug
          Components: Java Broker, Java Tests
            Reporter: Keith Wall
            Priority: Minor


Tes MultiNodeTest#testQuorumOverride is racey.    The test verifies the behaviour of a group when all the replicas are killed and quorum override is applied to allow the master to continue in isolation.

The test currently assumes that failover doesn't occur.  This is wrong, failover may occur is the master discovers itself alone before the quorum override is applied.  This discovery is asynchronous.  The test cannot predict if failover will occur of not.

In the unlucky case where failure occurs, the the failover happens whilst the test is committing a transaction. The transaction will correctly.  The test does include code to retry failed transactions.
