Subject [jira] Created: (HARMONY-2593) [classlib][swing][plaf] javax.swing.plaf.basic.BasicTextAreaUI exceptions incompatible with RI
Date Mon, 11 Dec 2006 11:45:21 GMT
[classlib][swing][plaf] javax.swing.plaf.basic.BasicTextAreaUI exceptions incompatible with

                 Key: HARMONY-2593
                 URL: http://issues.apache.org/jira/browse/HARMONY-2593
             Project: Harmony
          Issue Type: Bug
          Components: Classlib
            Reporter: Anton Luht
            Priority: Minor

There are at least two differences in behaviour of BasicTextAreaUI between RI and Harmony:
- new BasicTextAreaUI().getPreferredSize(new JComponent(){}) throws NPE in RI and IllegalArgumentException
in Harmony
- new BasicTextAreaUI().installUI(new JComponent(){}) throws Error in RI but works silently
in Harmony

Code to reproduce:

import javax.swing.*;
import javax.swing.plaf.basic.*;

public class Test {
        public static void main(String args[]) {
              JComponent jc = new JComponent() {};
              BasicTextAreaUI bta = new BasicTextAreaUI();

              try {
              } catch(Throwable e) {
                 System.err.println("exception 1");

              try {
              } catch(Throwable e) {
                 System.err.println("exception 2");

Output in RI:

Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_06-b05)
Java HotSpot(TM) Client VM (build 1.5.0_06-b05, mixed mode)
