[concurrency-interest] Basic question on making a thread waiting for 2 mailboxes...

I used to write real time apps using RSX11M+ (and VMS) that had mailboxes
and events. There was a "wait for OR(events)". The task would wait for any
event specified in the OR. Then I would associate an event with a mailbox,
do that for another mailbox and when a message would arrive in one of the 2
mailboxes, the task would awake. I am trying to do that in Java with
I have been reading "Java Threads", "JCIP", "Java in a Nutshell" and I
could think about a couple of classes I could use but I would appreciate
some design advice... Or if there is an existing library that does that
already does that, I would appreciate a reference, I did some research and
did not find anything interesting.
Basically I need 1 public mailbox and 1 private mailbox for a thread. The
thread would be blocked until a message arrives in one of the mailboxes. The
mailboxes must have multiple slots. I was thinking about using
LinkedBlockingQueues as mailboxes since I don't want to block the sender (or
avoid it) but I am a bit stuck on making the thread wait for a message in
The next step would be to have a ThreadPool for the tasks, sharing a common
public mailbox to process the messages and each have a private mailbox for
system management messages. I guess switching to a single thread to a
ThreadPool would be relatively easy?
Thanks in advance.
