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

             Summary: ClassCastException in ProtobufMetadataManagerInterceptor for clear
                 Key: ISPN-5993
                 URL: https://issues.jboss.org/browse/ISPN-5993
             Project: Infinispan
          Issue Type: Bug
          Components: Server
    Affects Versions: 8.1.0.CR1
            Reporter: Dan Berindei
            Assignee: Adrian Nistor
            Priority: Minor
             Fix For: 8.1.0.Final


When handling a {{ClearCommand}}, {{ProtobufMetadataManagerInterceptor}} tries to lock the {{.errors}} key explicitly, but because the clear operation now ignores transactions, the invocation context is not transactional, and the lock fails. 

Normally the protobuf cache should never be cleared, but it does happen when the test suite clears the caches before shutdown:
