Distributable MES

[glassfishrobot]

Discuss whether we need to bring back distributable ManagedExecutorService in the next revision of the concurrency EE spec.

One question that was brought up is how one server instant can retrieve the Future to cancel a long-running task if the task was originally submitted by another server instance.

Adding some context here (without endorsing the idea) from a PDF on JSR 236:

• Same rules as a ManagedExecutorService
• Allows distributing the task to a peer on another
  server instance (JVM).
• Task must implement serializable
• Optional feature – Java EE Providers do not have to
  supply a distributable ManagedExecutorService.
• Two distributable types are available:
• With and without affinity
• Tasks could provide distributable hint to Java EE
  product providers through executionProperties in
  ManagedTask.
