[OPENEJB-1119] OutOfMemoryError when creating many one time timers in timed session ejb

• Type: Bug

Description

Example: Create a timed session bean with a one time (single-action) timer - in a finally block of the ejbTimeout method recreate timer with same info serializable and interval. So this construct represents my scheduled interval job for doing some task again and again.

When calling the sessioncontext.getTimerService().getTimers().size() always 1 is returned.

My profiler tells me, with every sessioncontext.getTimerService().createTimer(interval, info) method call, some OpenEJB objects like:

org.apache.openejb.core.timer.TimerData
org.apache.openejb.core.timer.TimerData$TimerDataSynchronization
org.apache.openejb.core.timer.TimerImpl
org.apache.geronimo.transaction.manager.XidImpl

and some more (about 20 classes) are created and never removed.

This finally leads to an OutOfMemoryError.
When defining ejbTimeout method TX NotSupported than I couldn't reproduce this issue.

Hope this helps, greetings
