I am getting a VM crash when shearing a group containing a rectangle and text over a range of values specified by a slider. When I move the thumb of the slider, shear transform is applied on the group as follows - shear (slider.val, slider.val). When I move the slider to the maximum value, VM crashes. 

I tested with SDK build - 261 on Vista using 6u10-b22. This is reproducible on jdk6-FCS as well.

To reproduce the bug, run the attached test on the latest SDK and move the slider thumb slowly towards the right (till the max value is attained). You will see the app crashing when slider moves towards the max value. 

I have been trying to reproduce this with Scenegraph test but still have not succeeded.


Here is the crash dump-
