This enhancement proposal addresses three separate issues with the RpcChannel
tribes component.
1. There is a minor bug in a catch(InterruptedException) clause, in which a
call to Thread#interrupted() is made, as opposed to Thread#interrupt(), as it
should be.
2. The RpcChannel API user registers an RpcCallback to be notified of
communication events. However, there is no callback method for the case where
the sending of a response message fails. This proposal includes the addition of
a corresponding callback for such cases. To ensure backwards-compatibility, the
additional callback method has been declared in a sub-interface of RpcCallback,
named RpcCallback2 for the time being.
3. Since the tribes classes are loaded by the tomcat loader, if the messages
sent through tribes are instances of classes defined in the webapp, attemps to
deserialize them will fail. AbstractReplicatedMap includes a mechanism for the
API user to specify class loaders to be used when deserializing map entries.
This enhancement proposal includes a similar mechanism for the RpcChannel.
Please find the proposed modifications attached.
