[jboss-jira] [JBoss JIRA] Updated: (JBCACHE-766) Don't return unnecessary values from _replicate, avoiding need for marshalling

Don't return unnecessary values from _replicate, avoiding need for marshalling ------------------------------------------------------------------------------ Key: JBCACHE-766 URL: http://jira.jboss.com/jira/browse/JBCACHE-766 Project: JBoss Cache Issue Type: Patch Security Level: Public(Everyone can see) Components: Clustering Affects Versions: 1.4.0.SP1 Reporter: Owen Taylor Assigned To: Manik Surtani Priority: Minor Fix For: 1.4.0.SP2 Attachments: jbosscache-avoid-return-20060912.patch This is somewhat related to JBCACHE-752, which suggests setting a marshaller for responses passed over RpcDispatcher as well as for requests, but is a simpler and less general fix. Right now if you set a class loader for a tree cache region, it works for request parameters, but is ignored for returns. If there is an attempt to return a value that needs to be loaded with the class loader, an exception will be thrown. The only return value in normal REPL_SYNC operation is the return value from the key-value put methods, which is the old value, if any. But that return value isn't needed for replication. So, this patch just nulls out the return value from the two affected methods. (We're setting a class loader to deal with the fact that enumerations fields of Hibernate entities are stored directly in the cache, and are serialized/deserialized on replication. There's a JIRA entry for that issue, which likely should be fixed in Hibernate by storing such fields as ordinals, but I think this patch is a legitimate TreeCache fix, if done in a slightly hacky manner.)
