Hi there.

I've written a custom Preferences implementation for my Java 1.4 
application which uses a relation database as a backing store.  During 
the app's startup, I make this known to the app by setting the 
appropriate sysyem property:

System.getProperties().
setProperty("java.util.prefs.PreferencesFactory",
"com.dw.util.prefs.MyPreferencesFactory");

I noticed that if my app attempted to bring up any UI before this system 
property is set, the default (linux or windows) preferences 
implementation would beat mine to the punch.  My system preference gets 
set, but it's too late, another preferences implementation has beat mine 
to the punch because some other entity requested a preference node.

The real problem is that I need to identify and authenticate my user 
before I can build the "user root" Preferences node.  To do this, I 
bring up a login dialog.  For some reason, bringing up the dialog 
results in a call PreferencesFactory.userRoot().  I don't understand 
this--why would AWT want to have anything with java.util.prefs?

This stack trace tells the story.  I'm simply trying to show a splash 
screen and sun.awt.im.ExecutableInputMethodManager makes a getUserRoot() 
call before I'm ready for it:

Any insight is much appreciated.
