Using the java.util.prefs classes with a server run as user nobody and group
nobody where I don't want to create a user prefs directory (and it looks like the
java vm doesn't have appropriate user privs to do it at the OS level anyway)
causes threads to complain often:

This makes it difficult if not impossible to use the java.prefs classes in a
server. These warnings also have a significant impact on performance.
