[OpenJDK 2D-Dev] [9]Fix for JDK-8158356 : SIGSEGV when attempting to rotate BufferedImage using AffineTransform by NaN degrees

[Phil Race]

1) The spec for the constructors needs to be updated to include this
reason for throwing ImagingOpException. A CCC request will be needed.

2) The C usage of "isnan()" may be problematic in some compilation 
environments.
For example I believe this will not compile with VS2010, and many folks 
still use that.
Instead you could use matrix[j] != matrix[j] as the two values should 
not compare
equal if it is NaN.
