[classlib][swing] j.s.text.JTextPane.updateUI() throws NPE
----------------------------------------------------------

                 Key: HARMONY-2521
                 URL: http://issues.apache.org/jira/browse/HARMONY-2521
             Project: Harmony
          Issue Type: Bug
          Components: Classlib
            Reporter: Alexey A. Ivanov


import javax.swing.JTextPane;

public class Test {
    public static void main(String[] args) {
        new JTextPane().updateUI();
        System.out.println("passed OK");
    }
}


This simple code causes NPE on Harmony:
