Good day to you.
Request your time in reviewing a minor fix for the bug
. Bug: https://bugs.openjdk.java.net/browse/JDK-8198613
. Title: Test cases result in failure or timeout when run with OpenGL backend
. OpenGL is not the default backend (or) the pipeline of choice for Java on different platforms.
. However, we have been running many test cases enabling OpenGL with VM option -Dsun.java2d.opengl=True, on all the platforms which results in failures or time outs on many occasions.
Information on the Fix:
. Kindly refer to the mail thread capturing review suggestions for a similar bug- JDK-8196451
. Discussion Link: http://mail.openjdk.java.net/pipermail/2d-dev/2018-February/008932.html
. To stabilize our test suite, we need not enable OpenGL pipeline where OS+OpenGL isn't the supported configuration.
. If required, OpenGL pipeline could be enabled by using -vmoptions:"-Dsun.java2d.opengl=True" with Jtreg command.
. As a follow-up from the discussion, I've now removed the VM option -Dsun.java2d.opengl=True for the test cases.
. In addition, the test cases that were dedicated for OpenGL backend (in open/test/jdk/sun/java2d/OpenGL) have been moved to appropriate directories namely- open/test/jdk/java/awt/image/VolatileImage (or) open/test/jdk/java/awt/Graphics2D.
Information on Testing:
. The modified test cases have been tested on: Win-10, Win-10 (with hidpi), Win-7, Linux Ubuntu-16.04, Mac Sierra 10.12 platforms.
. Based on the test results, ProblemList.txt has been updated and has been captured as a part of this webrev.
Kindly review the changes at your convenience and provide your feedback
Thank you for your time in review
Have a good day
