Nooooooo. I am thinking of something else. Sorry, my bad. sleep()
MUST... NOT... THROW...
What Ken said was correct:
public void sleep() {
try {
// your code here
} (Exception e) {
logger.error("Exception thrown in sleep code", e);
} finally {
super.sleep();
}
}

OK. thanks. I have implemented that in sleep and my Session
subclasses. .... except I added a catch and log.error aswell so we
will get an email if I get an error in sleep() So we will
see ........ it might be a year before I see this error again .....
if you have no catch statement as shown in your example won't this
throw anyway?
It will throw, but the important part is that super.sleep() will be
called whether it throws or not.

You mean wrap contents of sleep and terminate with try/catch and
don't throw, just log it?
That is what I started doing long ago. I think this is a better
solution:
public void sleep() {
try {
// your code here
} finally {
super.sleep();
}
}

MultiECLockManager still had it locked, it may not be able to.
I don't use ERXEC so I really don't know. Check your Sessions()
sleep() and terminate() methods (and any super class you have)
to ensure that they can't throw an exception.
