The proposed approach seems overkilling when the following change would achieve the same without introducing new concurrent logic: * The CallableQueueService would define a PriorityQueue with 4 priorities instead of 3. * The queue() method would ensure there no command being queued has priority 4 (forbidding direct use of the the highest priority). * The CallableQueueService would a new protected method 'Set<Class> getInterruptCommandClasses()' that would return the commands that are 'interrupt' commands. * On Queuing, within the queue() command any command which class is in the above Set will be bumped to priority 4. This achieves exactly the same behavior with the current well tested logic. - Alejandro On 2011-12-09 18:58:56, Mohamed Battisha wrote: > > ----------------------------------------------------------- > This is an automatically generated e-mail.
