Description
We are using Quartz 1.8.3 with the Job Initialization Plugin.
After a few weeks of runtime we get an exception (see stacktrace below). The exception seems to
be caused by a Java bug:

This is not a problem with Quartz. It is either a bug (as noted above) with the JVM, and or the
operating system's setting for max file handles (i.e. ulimit).
This can be resolved in various ways on different OSs.
For example:

it could also be a bug in your application not properly closing the files it opens.
