In this case I can say that it was nothing to do with being slow .. it is a driver bug.


Even if behavior depends from the driver does not mean that it is a bug in driver, we could do something wrong as well(since we have a bunch of artifacts in opengl pipeline on windows/linux). But if we do not want to invest time to investigate the reason of falure of this test on unsupported config(win+opengl) then I assume the same decision will be done for other possible failures as well. I suggest to drop "-Dsun.java2d.opengl" option from our tests instead of excluding the tests by keyword, so the tests will cover default system pipeline(which is supported), and it will cover opengl on mac as well. If it will be necessary to run the tests using some specific pipeline it will be possible to pass a parameter to jtreg to run all the tests using one pipeline.

Hi, Prahalad, Phil.
Maybe it is possible to add a log from jtr file to the bug report, usually it contains a stack trace on timeout. I am not sure that it is a good idea to update any tests without reproducing it, when we know that at least on one system it could be reproduced. The reasons maybe a slow virtual system and we need to update a timeout.

Hello Everyone

Good day to you.

Request your time in reviewing a minor change for a test bug

     [JDK-8196451]  sun/java2d/OpenGL/DrawBufImgOp.java times out

https://bugs.openjdk.java.net/browse/JDK-8196451

Observation:

     . The bug reports a test case- DrawBufImgOp, failing with Timeout error on Win7 and OpenGL backend.

     . The issue wasn't reproducible despite multiple test runs on Win7 and Win10 machines.

     . Hence OpenGL driver issues on the host machine is suspected to have resulted in this Timeout.

Code change:

     . The code changes add a new keyword- “opengl” to TEST.ROOT and the respective test case.

     . Since D3D is the preferred back-end on Windows, this keyword will be helpful to filter OpenGL tests from execution in future.

     . Note: There are many bugs that are similar to the current one. But it’s hard to propose a common fix as some of the test cases execute with multiple @run tags (one for every back-end).

Kindly review the change and suggest your views

Thank you for your time

Have a good day
