Resolution: Won't Fix
> [classlib][awt] Compatibility: java.awt.GraphicsDevice.getDisplayMode() on RI throws unspecified NPE while Harmony doesn't
> --------------------------------------------------------------------------------------------------------------------------
>
> Key: HARMONY-2610
> URL: https://issues.apache.org/jira/browse/HARMONY-2610
> Project: Harmony
> Issue Type: Bug
> Components: Non-bug differences from RI
> Reporter: Ilya Okomin
> Assigned To: Alexei Zakharov
> Priority: Minor
>
> Harmony for java.awt.GraphicsDevice.getDisplayMode() does not throw unspecified NPE while RI does.
> Test case for reproducing:
> ------------------ test.java -----------------
> import junit.framework.TestCase;
> import junit.textui.TestRunner;
> import java.awt.GraphicsDevice;
> import java.awt.GraphicsConfiguration;
> public class test extends TestCase {
> public static void main(String args[]) {
> TestRunner.run(test.class);
> }
> private static class TestGraphicsDevice extends GraphicsDevice {
> public int getType() {
> return GraphicsDevice.TYPE_IMAGE_BUFFER;
> }
> public String getIDstring() {
> return "A";
> }
> public GraphicsConfiguration[] getConfigurations() {
> return new GraphicsConfiguration[0];
> }
> public GraphicsConfiguration getDefaultConfiguration() {
> return null;
> }
> }
> public void testRun() {
> TestGraphicsDevice localTestGraphicsDevice = new TestGraphicsDevice();
> try {
> System.out.println("Display mode = " + localTestGraphicsDevice.getDisplayMode());
> fail("NPE Expected!");
> } catch (NullPointerException e) {
> e.printStackTrace();
> }
> }
> }
> ----------------------------------
> Output RI:
> ========
> .java.lang.NullPointerException
> at java.awt.GraphicsDevice.getDisplayMode(GraphicsDevice.java:271)

> at junit.textui.TestRunner.run(TestRunner.java:72)
> at junit.textui.TestRunner.run(TestRunner.java:57)
> at test.main(test.java:12)
> Time: 0,04
> OK (1 test)
> Output Harmony:
> =============
> .Display mode = java.awt.DisplayMode@2079f204
> F
> Time: 0.04
> There was 1 failure:
> 1) testRun(test)junit.framework.AssertionFailedError: NPE Expected!
> at test.testRun(test.java:36)
> at java.lang.reflect.VMReflection.invokeMethod(Native Method)
> at test.main(test.java:10)
> FAILURES!!!
> Tests run: 1, Failures: 1, Errors: 0
> IMO this bug can be marked as non-bug difference, since Harmony creates DisplayMode object with default parameters and RI throws unspecified exception. Any thoughts?
