Preferences object calls junks directories

[Vinaya Thimmappa Kumar]

I am using Prefernces object and creates junk directories under
/etc/.java/.systemPrefs

ls /etc/.java/.systemPrefs/
> > > .system.lock
> > > .systemRootModFile
> > > _!':!bw"t!#4!a!"w!#4!bw"2


my java code is

> > > -----------------
> > > import java.util.prefs.*;
> > >
> > > class Pref
> > > {
> > > static public void main (final String[] args)
> > > {
> > > String prefsStr = new String ("machine/domain");
> > > Preferences prefs = Preferences.userRoot ();
> > > prefs = prefs.node (prefsStr);
> > > prefs.putInt ("Variant", 1);
> > > try {prefs.flush ();}
> > > catch (BackingStoreException ex)
> > > {
> > > System.out.println ("Flush Exception " + ex);
> > > }
> > > }
> > > }
> > >

Why do you care?
The whole idea of java.util.Preferences is to isolate you (the developer) from these kind of implementation details. If you really really want to care, simply look at the source for your distribution. I'm sure the answer lies therein.
