[OpenJDK 2D-Dev] [9] RFR JDK-8166685: We should unpin stream and pixel buffer in case of setjmp during writeImage in JPEG.

[Jayathirth D V]

Hi,

 

Please review the following fix in JDK9 at your convenience:

 

Bug : https://bugs.openjdk.java.net/browse/JDK-8166685 

 

Webrev : http://cr.openjdk.java.net/~jdv/8166685/webrev.00/ 

 

Issue : As part of fix for JDK- 8162461 we removed RELEASE_ARRAYS() in 
writeImage() call in imageioJPEG.c for setjmp case.

 

Root cause : We can perform non-local jump to setjmp from longjmp during 
anytime in write process. If there is no RELEASE_ARRAYS() call then it might 
crash JVM as it was happening in JDK- 8162461.

 

Solution : We should have RELEASE_ARRAYS() call in setjmp case for writeImage() 
in imageioJPEG.c.

 

Thanks,

Jay
