[jira] Created: (HIVEMIND-208) Service Serialization doesn't work on a cluster

Service Serialization doesn't work on a cluster
-----------------------------------------------

                 Key: HIVEMIND-208
                 URL: https://issues.apache.org/jira/browse/HIVEMIND-208
             Project: HiveMind
          Issue Type: Bug
          Components: framework
    Affects Versions: 1.1.1
            Reporter: Hugo Palma
            Priority: Critical


I'm getting the following exception all over the logs in a clustered environment :

org.apache.hivemind.ApplicationRuntimeException: The ServiceSerializationSupport instance has not been set; this indicates that the HiveMind Registry has not been created within this JVM.

It seems that the cause might be the use of a LocalThread variable in ServiceSerializationHelper.

Has anyone found a workaround for this issue?

Do you have to provide your own persistence mechanism
by implementing a 'private void writeObject(ObjectOutputStream s) throws IOException' method and setting
the service to null so the service is not persisted?

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

Have gotten a test case to emulate this and it looks (at an initial glance) that the problem disappears if replacing the thread local with a simple instance variable that is accessible to any of the threads.  Not been able to test in a real environment.

Will attach patch - comments are appreciated.
