             Summary: PessimisticTxPartitionAndMergeDuringRollbackTest.testDegradedPartitionWithDiscard
                 Key: ISPN-8646
                 URL: https://issues.jboss.org/browse/ISPN-8646
             Project: Infinispan
          Issue Type: Bug
          Components: Test Suite - Core
            Reporter: Pedro Ruivo
            Assignee: Pedro Ruivo


The discard filter isn't working properly. the discard is only expects (and discard) a single command but if the retries happens to fast, the discard let it go through. 

this may be the cause of the other *discard* related failures in this package
