             Summary: RHQ server plugin: synchronize data operation String casting to Byte array fails
                 Key: ISPN-4448
                 URL: https://issues.jboss.org/browse/ISPN-4448
             Project: Infinispan
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: JMX, reporting and management
    Affects Versions: 7.0.0.Alpha4
            Reporter: Tomas Sykora
            Assignee: Mircea Markus


Invocation of rolling upgrades related operation -- Synchronize Data -- on a new node's cache fails with a following error:

java.lang.Exception: JBAS011002: Failed to invoke operation: java.lang.String cannot be cast to [B, rolled-back=true
	at org.rhq.core.pc.operation.OperationInvocation.run(OperationInvocation.java:278)
	at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1110)
	at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:603)
	at java.lang.Thread.run(Thread.java:722)


Note, that there is also ISPN-4447 which says, that we can't record known global keyset using RHQ. 

In this issue, we proceed that operation using CLI interface console in order to create dumped keys. Then, we tried to synchronize data using RHQ cache operation and passing "hotrod" as a migrator. This was expected to work properly.
