Subject [lang] Concurrency utils for JDK 1.5+ version
Date Sat, 24 Jan 2009 16:37:29 GMT
Since Java 1.5 there is a lot of functionality in the area of thread 
synchronization and multi-threaded programming. However, there are 
certainly still missing features or APIs that could be improved or made 
easier to use.

How about adding such features to an upcoming version of Commons Lang? 
What I have in mind is things like the following:

* Some utility methods related to ExecutorServices, e.g. handling of 
ExecutionException, shutting down an executor and waiting for its 
termination, etc.
* A generic(s) implementation of the lazy initialization pattern.
* A caching service offering more concurrency when creating the objects 
to be cached is expensive.
* Maybe some specialized synchronization primitives.

Surely more points can be added to this list.
