A DESCRIPTION OF THE PROBLEM :
A custom javax.swing.Icon implementation which sets a TexturePaint on a Graphics2D and calls fillPolygon afterwards throws a java.lang.InternalError when the icon is being painted.

REGRESSION. Last worked in version 7u71

ADDITIONAL REGRESSION INFORMATION:

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run the attached code

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
A JFrame containing a JLabel with a custom Icon and some text
ACTUAL -
An InternalError is being thrown with message: Surface not cachable
