Description

Though I was not able to investigate it completely, while investigating the cause of CONTINUUM-2742, it appears that quartz schedulers are leaked in addition to the ones from CONTINUUM-2742.

Fortunately, even with the large number of startup/shutdown cycles PlexusTestCase tests cause in continuum-core, they are not generating a number large enough to cause system instability.

They may be disposed of cleanly when the JVM finishes due to the org.quartz.plugins.management.ShutdownHookPlugin configured in continuum-webapp while running in continuum-webapp. Regardless of whether this is true, it would be better to drop the threads as soon as possible. This is especially true if new threads are generated by reconfiguring schedules in continuum-webapp's UI, because it would have a cumulative effect over time.
