[jboss-jira] [JBoss JIRA] Closed: (JBCACHE-754) RPC return values to use a marshaller as well

RPC return values to use a marshaller as well --------------------------------------------- Key: JBCACHE-754 URL: http://jira.jboss.com/jira/browse/JBCACHE-754 Project: JBoss Cache Issue Type: Feature Request Security Level: Public(Everyone can see) Affects Versions: 2.0.0, 1.4.0 Reporter: Manik Surtani Assigned To: Manik Surtani Fix For: 2.1.0 Original Estimate: 3 days Remaining Estimate: 3 days Currently, all RPC calls go through the VersionAwareMarshaller which is responsible for efficiently marshalling JBC internal objects as well as user objects using JBoss Serialization. Return values and exceptions, on the other hand, are marshalled/unmarshalled using JGroups' Util.{to|from}ByteBuffer() which uses standard object serialization. The problems here are twofold: 1) Relatively inefficient (in speed as well as byte array size) marshalling/unmarshalling for return values 2) Potential class loader problems Most RPC calls in JBoss Cache do not have return values so this is not a problem that comes up often, but certain features (clustered cache loader, data gravitation in buddy replication) rely on return values. The solution to this problem is to be able to register a marshaller with the JGroups RPCDispatcher for return values (and exceptions) as well as for the RPC calls themselves.
