FULL PRODUCT VERSION :
java version "1.7.0_45"
Java(TM) SE Runtime Environment (build 1.7.0_45-b18)
Java HotSpot(TM) Client VM (build 24.45-b08, mixed mode, sharing)

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows [Version 6.1.7601]
We've seen this on Win XP, Vista, 7 and 8. The display adapter seems to be the key element.


EXTRA RELEVANT SYSTEM CONFIGURATION :
Display adapter:
AMD Radeon HD 7660G
ATI Mobility Radeon HD 3470
nVidia Quadro NVS 110M

Does NOT happen with
Intel HD graphics 2500
Mobile Intel(R) 965 Express chipset family

A DESCRIPTION OF THE PROBLEM :
"java.lang.InternalError: not implemented yet" when first invoke "SunGraphics2D.drawRect" on mouseMoved with Xor mode enabled, using certain display adapters..

ADDITIONAL REGRESSION INFORMATION:
This seems to be related to JDK-7153339 : InternalError when drawLine with Xor and Antialiasing

These are our testing results on affected machines. "line" refers to the drawLine test in bug 7153339, while "rect" refers to the drawRect test attached to this bug report.

7u25: "Unable to stroke" with both line & rect
7u45: no errors with line and "not implemented yet" with rect
8b111: no errors with line and "not implemented yet" with rect



STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Compile and run the test program provided being sure to use one of the indicated graphic display adapters.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
no errors
ACTUAL -
"InternalError: not implemented yet" on first invoke of drawRect

CUSTOMER SUBMITTED WORKAROUND :
Catch the InternalError and silently ignore it if it's the "not implemented yet" one. The effect is that the rectangle is not drawn initially on affected machines but it's hard to notice and definitely better than the exception.
