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: William Burns Labels: rhq 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.
