FULL PRODUCT VERSION :
vm_info: Java HotSpot(TM) 64-Bit Server VM (23.21-b01) for windows-amd64 JRE (1.7.0_21-b11), built on Apr 4 2013 08:11:28 by " java_re " with unknown MS VC++:1600

ADDITIONAL OS VERSION INFORMATION :
OS: Windows 7 , 64 bit Build 7601 Service Pack 1

A DESCRIPTION OF THE PROBLEM :
Providing a NaN rotation in the affine transform in the FontRenderContext causes Font.getStringBounds() to crash (on Windows only)

The obvious workaround is not to provide a NaN, of course. But I humbly suggest that it should still not crash the entire JRE.
