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

             Summary: MarshalledValue fails to compare the correct buffer region of non-exactly predicted buffer sizes of ExpandableMarshalledValueByteStream instances
                 Key: ISPN-2193
                 URL: https://issues.jboss.org/browse/ISPN-2193
             Project: Infinispan
          Issue Type: Bug
          Components: Core API, Distributed Cache, Marshalling, RPC
    Affects Versions: 5.1.5.FINAL
            Reporter: Sanne Grinovero
            Assignee: Sanne Grinovero
            Priority: Blocker
             Fix For: 5.1.6.FINAL


This problem was spotted by the Hibernate 2nd level cache testsuite.

Since the introduction of ExpandableMarshalledValueByteStream as an improvement to MarshalledValue, the war buffer might be allocated larger than the actually used buffer region. Most usages of getRaw() where correctly using the area, except the final line of the equals implementation of MarshalledValue - which is reached only in exceptional cases and configurations.
