[infinispan-dev] distributed execution - invoking commands on self

Hi, I discovered a problem with distributed framework in cases where Callables submitted for distributed execution contain mutable instance fields. Just before Callable is dispersed across cluster it gets invoked locally where instance fields of a submitted Callable can be possibly mutated; Callable is in turn sent to remote nodes with mutated values instead of "original" field values as submitted by user. For example, consider pi approximation example from wiki [1]. If CircleTest Callable declared insideCircleCount as an instance field instead of local field of call method we would ultimately get a wrong final result. Therefore we need to ensure that each Infinispan node gets an unmodified instance of Callable for execution. I was looking at the possibility to send command to self thus causing creation of a marshaled copy of a Callable, pretty much like any other remote node receives it. However, I was unable to invoke a command on self. Any way to do this? How about invoking marshaling locally to create a Callable copy without going through rpc invocation layer? I though about skipping master/self node altogether but that's an easy way out;-) Got suggestions, ideas? Regards, Vladimir [1] http://community.jboss.org/wiki/InfinispanDistributedExecutionFramework
