However, I don't have any real experience with ThreadLocal, and when a neophyte agrees with your argument, that's a red flag. Here's a blog where someone seems to have the same issue as you. <http://weblogs.java.net/blog/jjviana/archive/2010/06/10/threadlocal-thread-pool-bad-idea-or-dealing-apparent-glassfish-memor> At the end of the comments, there's a suggestion to use ThreadLocal::remove(), with the implication that it allows the thread local variable to be garbage collection. Is there a reason that doesn't work for you? My other thought is that "for the current thread" could be improved with "for a given thread." So, inside an Executor, I can just call Thread t = ... // .. use the thread .. Thread.removeLocals( t ); // now add the thread back into the pool... And this seems better because I don't have to rely on the users of a thread remembering to do it themselves. External control seems better here.
