Description

The key stores factory starts a timer for monitoring file changes that should be reloaded.  The call to destroy() doesn't cancel the timer when a trust manager isn't defined.  This leaves the timer running, during shutdown.  This can be seen in unit tests that do not stop when the test completes.
