PIT: Volatile Image's ImageCap.isTrueVolatile() returns false on Win32

I am creating an opaque volatile image and rendering it on a JComponent. I am getting the ImageCapabilities object from this volatile image and calling ImageCap.isTrueVolatile(). On the PIT build given below, this method returns false on WinXP-sp2.

java version "2d.pit-jcg-win-03-2005-04-09.mustang"
Java(TM) 2 Runtime Environment, Standard Edition (build 2d.pit-jcg-win-03-2005-04-09.mustang)
Java HotSpot(TM) Client VM (build 1.6.0-ea-b31, mixed mode)

This is reproducible only on the PIT build and not occuring on Mustag-b31.

I have attached a sample test. Execute the sample test. You would see a frame with a duke image. If the console shows that the volatile image is not accelerated, the bug is reproduced. I am using NVidia GeForce Mx4000 video card with the latest driver.

------ Here is the console output -----------------
On PIT Build: Default mode
--------------------------
From IMG: Is Accelerated? true
From IMG: Is True Volatile? false
From GC: Is Accelerated? true
From GC: Is True Volatile? true

On Mustang-b31: Default Mode
-----------------------------
From IMG: Is Accelerated? true
From IMG: Is True Volatile? true
From GC: Is Accelerated? true
From GC: Is True Volatile? true
----------------------------------------------

On PIT build: OpenGL Mode
-------------------------
From IMG: Is Accelerated? true
From IMG: Is True Volatile? false
From GC: Is Accelerated? true
From GC: Is True Volatile? true

On Mustang-b31 : OpenGL Mode
----------------------------
From IMG: Is Accelerated? true
From IMG: Is True Volatile? true
From GC: Is Accelerated? true
From GC: Is True Volatile? false
