Alexei Zakharov commented on HARMONY-3602:
------------------------------------------

Andrey, in this I suppose we should add the above test to the Harmony test base.

> The following piece of code causes the current thread to be interrupted:
> public class Test {
>     public static void main(String args[]) throws Exception {
>         java.awt.Image img = java.awt.Toolkit.getDefaultToolkit().createImage(Thread.currentThread().getContextClassLoader().getResource("test.gif"));
>         new javax.swing.ImageIcon(img); // Loads the image.
>         img.flush(); // ERROR: Calls Thread.currentThread().interrupt().
>         System.out.println(Thread.currentThread().isInterrupted() ? "FAIL" : "SUCCESS");
>     }
> }
> Please put the attached test.gif (it's a trivial image, nothing special, but it should
exist) to current directory before running the test.
> The stack of calls causing the current thread to be interrupted is:
> 	org.apache.harmony.awt.gl.image.ImageDecoder.terminate() :128
> 	org.apache.harmony.awt.gl.image.DecodingImageSource.removeConsumer(ImageConsumer) :105
> 	org.apache.harmony.awt.gl.image.OffscreenImage.stopProduction() :426
> 	org.apache.harmony.awt.gl.image.OffscreenImage.flush() :133
> Probably ImageDecoder.terminate() should not use Thread.currentThread() do determine
a thread to interrupt.
> Output on RI:
> SUCCESS
> Output on Harmony/IBM VM:
> SUCCESS
> Output on Harmony/DRL VM:
> FAIL
> This looks like a clear AWT problem, however the problem only occurs on DRL VM, so probably
some issue (race condition, lack of synchronization or something like that) exists there also.
> The problem was discovered while trying to run NetBeans on Harmony.
