Any ideas why the user is seeing this behavior with the Timer service?

You want to field this one? Here's a case where a user is taking your
basic example, timersession, and is trying to extend/enhance it. (But
she's encountering problems.) If you solve the problem, maybe it is
worth a look into whether you want to add it as an enhancement to the
example?

comments: I run the timersession example.
As to try a more real life example I then changed the TimerSessionBean so instead of a single event the timer will run a repeatative mode. I did that by changing the code to:
Timer timer = timerService.createTimer(0, intervalDuration, "Created new timer");
As to follow up on the accuracy of the events I've enhanced the log to:
logger.info(System.currentTimeMillis() + ": Timeout occurred");
The client doClient method is configured to call the bean with a value of 3000[mSec]
To my suprise the events are triggered every 7[sec] rather then 3[sec]
1188315664484: Timeout occurred
1188315671562: Timeout occurred
1188315678578: Timeout occurred
1188315685578: Timeout occurred
1188315692593: Timeout occurred
I've run similar Time mechansims based on MBean infrastructure and it workes perfectly so the issue is not with the hardware / OS / JVM.
Any suggestions
