[OpenJDK 2D-Dev] <AWT Dev> [12] RFR JDK-8176556: java/awt/dnd/ImageTransferTest/ImageTransferTest.java fails for JFIF

[Jayathirth D V]

Hello All,

 

Please review the following fix in JDK12 :

 

Bug : https://bugs.openjdk.java.net/browse/JDK-8176556 

Webrev : http://cr.openjdk.java.net/~jdv/8176556/webrev.00/ 

 

Issue : When we run java/awt/dnd/ImageTransferTest/ImageTransferTest.java if fails to get ImageWriter(Service provider) capable of encoding JFIF format.

 

Root cause: Support for alpha channel in JPEG is removed in HYPERLINK "https://bugs.openjdk.java.net/browse/JDK-8204187"JDK-8204187 and this causes DataTransferer to throw exception saying unable to get Service provided for ARGB channel in for Jpeg.

 

Solution : Use RGB image without Alpha channel. This regression test was written to verify image data before and after DnD, so removing alpha channel will not affect its purpose.

 

Thanks,

Jay
