FULL PRODUCT VERSION :
1.5.0_06
1.4.2 build 1.4.2-b28
1.6.0-beta2-86
1.5.0_07


ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows XP [Version 5.1.2600]
Microsoft Windows 2000 [Version 5.00.2195]


EXTRA RELEVANT SYSTEM CONFIGURATION :
Occurs on all versions of Windows on single headed machines which we have tested it on. On a double headed Windows XP machine it does not occur.

A DESCRIPTION OF THE PROBLEM :
The first time GraphicsDevice.getConfigurations() is called on a single header machine it takes 3 to 5 seconds. If it is called again on the same machine in a different Java session it takes slightly less time. If it is called again in the same Java session it takes a few milliseconds.

This has previously been reported in 2000 but the bugs are marked as "fixed".  A 3 second delay does not sound like "fixed" to us.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run the program supplied which calls GraphicsDevice.getConfigurations().

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
I would expect the program to print:


Starting....
Finished in 20 milliseconds


ACTUAL -
It actually prints:

Starting....
Finished in 3585 milliseconds


REPRODUCIBILITY :
This bug can be reproduced always.

	   // The second and subsequent calls in the same

	   System.err.println("Starting....") ;
	   long startTime = System.currentTimeMillis() ;
           GraphicsConfiguration[] gc = gs[j].getConfigurations();
	   System.err.println("Finished in "
			   + (System.currentTimeMillis() - startTime)
			   + " milliseconds"
			   ) ;
	   }
	}
}

---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
Spin up a separate thread which Thread.sleep()s until the main startup has finished and then executes a GraphicsDevice.getConfigurations(). All subsequent calls now complete in a few milliseconds.
