I am running an application which creates a TrayIcon and adds it to the SystemTray. I have the default security manager installed in the app and I have given necessary permissions such as AccessSystemTray and FilePermissions. When I am running the application on SolarisSparc10-JDS with the following PIT build, I am getting an IllegalMonitorStateException as given below:

java.lang.IllegalMonitorStateException
at java.lang.Object.notifyAll(Native Method)
at sun.awt.X11.XTrayIconPeer$5.dispatchEvent(XTrayIconPeer.java:172)
at sun.awt.X11.XToolkit.dispatchEvent(XToolkit.java:481)
at sun.awt.X11.XToolkit.run(XToolkit.java:625)
at sun.awt.X11.XToolkit.run(XToolkit.java:559)
at java.lang.Thread.run(Thread.java:611)

Here is the PIT build:
java version "1.6.0-internal"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.6.0-internal-df153228_09_Sep_2005_03_13-b00)
Java HotSpot(TM) Server VM (build 1.6.0-ea-b51, mixed mode)

This is reproducible only on XAWT and not reproducible on Win32. I reproduced it on SolSparc10-JDS.

I have attached a sample test. Execute the sample test. Make sure you have all the necessary permissions in the policy file. If you see the above exception on the console, the bug is reproduced. Click 'Add Icon' / 'Remove Icon' repeatedly. You would see the exception whenever you add the icon.
