[concurrency-interest] Executors and J2EE Work frameworks

Although at first I had my reservations about these specs, upon further 
review I believe they to be worthwhile efforts, and they should be 
carefully observed. I would like to see someone represent this 
community in either or both EGs, esp. the Work Manager group. With Work 
Management, a number of issues exist w.r.t. propagating transaction and 
security contexts between threads - managing run-as authentication and 
enabling concurrent propagation of a single transaction context 
immediately come to mind. With Timers, there are various issue with 
addressing timer thread management within a J2EE container in a general 
fashion. The spec proposals do not cover all of these, and if these 
specs can receive input and guidance from various experts, they can 
hopefully address thread and timer management within J2EE in a 
comprehensive manner.
