There is some odd bug in the JVM. Some, and I don't remember exactly
which, classes related to time/date open time zone resource files
repeatedly and they forget to close them. If this is done fast enough
(faster than the garbage collector reaches those files which get closed
when finalized), you get this error.

It might be something else though.
