[OpenJDK 2D-Dev] [8u Backport] Fix for JDK-8158356 : SIGSEGV when attempting to rotate BufferedImage using AffineTransform by NaN degrees

[Ajit Ghaisas]

Hi,

 

   This is a review request for 8u back-port of the fix done in JDK-9.

   

Bug : 

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

 

Root cause :

   The root cause of the crash is - NaN is converted to an integer and used as array index in mlib_ImageScanPoly.c.

 

Fix :

   The native method previously did not check the validity of the input double argument. Now, I have added a check for finite double values.

 

Webrev :

Regards,

Ajit
