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

[Ajit Ghaisas]

Hi,

    Bug : https://bugs.openjdk.java.net/browse/JDK-8158356

    Issue : AffineTransform using NaN value as input parameter results in 
SIGSEGV.

    Fix : Transformation matrix is checked for NaN values in 
AffineTransformOp.validateTransform().
             Also, at native level a separate check is made to return error in 
case of NaN values.

    Webrev : http://cr.openjdk.java.net/~aghaisas/8158356/webrev.00/

    Request you to review.

Regards,
Ajit
