Description of problem:

REST API and JMS API provide operations to run more commands at once. This ability should be reflected in Java Remote API as well.

For example, I will get "UnsupportedOperationException: The .execute(..) method is not supported on the remote api" when I use the following code:

List<Command<?>> cmds = new ArrayList<Command<?>>();
cmds.add(new StartTaskCommand(taskId, userId));
cmds.add(new CompleteTaskCommand(taskId, userId, null));
ExecutionResults responses = rc.execute(CommandFactory.newBatchExecution(cmds));

I know that there also exists CompositeCommand just for TaskCommands but I use it for example to get more information about the process:

cmds.add(new GetTasksOwnedCommand("bob", "fr-CA"));
cmds.add(new GetProcessInstanceCommand(procInstId));

With my own REST/JMS client I will get the right response but it is not possible to do this request with the provided Java Remote API.
