Summary: Time to wait for retrieving message is incorrect

Initial Comment:
I have an application that sends several messages at a
time to a queue in OpenJMS. Occasionally, I will get a
timeout error, even though I've specified the time to
wait to be as much as 20 minutes.

Taking a look at the source for class JMSSession, it
seems that there may be a bug in the algorithm used to
determine how long to block for when waiting for a
message. In the method retrieveMessage, the following
code block appears:

// wait for a specific period of time
_receiveLock.wait(wait);
long current = System.currentTimeMillis();
if (current >= end) {
breakOnNextRead = true;
} else {
// update the time to wait. If the value
// is zero then break on the next read
wait -= (end - current);
if (wait == 0) {
breakOnNextRead = true;
}
}

When the receive lock is interrupted and the specified
total time to wait hasn't passed yet, I think the
remaining time to wait should be updated to the
value "end - current", not "wait - (end - current)".
