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: 8.2.0.Alpha1 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 between methods: {noformat} 12:33:30,174 ERROR (testng-SecureServerFailureRetryTest:)
