Support for java.util.prefs.Preferences?

[Steve McLeod]

Here's some sample code that reproduces the problem:

package com.barbarysoftware.pokercopilot;
import java.util.prefs.Preferences;
public class ScratchSpace {
    public static void main(String[] args) throws InterruptedException {
        final Preferences preferences =
Preferences.userNodeForPackage(ScratchSpace.class);
        System.out.println("preferences = " + preferences);
    }
}

Java 6 - code completes fully. Java 7 - exception thrown as per the
stack trace in the original message.
