WORK AROUND There are several workarounds for this problem: 1)Create the standart system prefs directory <etc/.java/.systemPrefs> manually. 2)Specify an alternate system prefs directory where user has write permission, via the System Property java.util.prefs.systemRoot . 3)Reduce the frequency of the warnings with the System Property java.util.prefs.syncInterval(the sync interval in seconds, which defaults to 30).
