<AWT Dev> Review request for 8048171: Test java/awt/Mixing/AWT_Mixing/OpaqueOverlappingChoice.java fails on solaris, linux but passes on windows

Tue Nov 3 13:07:06 UTC 2015

Hi Semyon,

                The issue with Choice which I mentioned, is my observation for the test failure. There is no bug reported.

                Regarding the test failure, because mouseClicked() was not getting called at all.

                Without the  fix, the test was failing with below log,

                                                Expected: 010000101

Observed: 

java.lang.RuntimeException: Opacity test mismatchs

                Reason: mouseClicked() was not getting called at all for Choice, hence 'testSeq' variable was not getting updated.

                But As per your observation, mouseClicked or mousePressed is getting called twice.

                There is a difference in behavior for event.

                The cause of this difference in behavior should be identified before proceeding further.

                Please provide any inputs if possible.

Many Thanks,

Ambarish

Hi Ambarish,

Thank you for the clarification. But on my Ubuntu 14.04 test fails before and after the fix due to the same reason: mouse click or press is fired twice. Could you send me link to the Choice issue you've mentioned?

Hi Semyon,

                OpaqueOverlapping :: performTest() function performs the test by generating mouse click event using,

                mouse press & mouse release events.

                But choice receives only mouse Press and mouse release event & does not receive the mouse clicked event.

                The test already does an adjustment for this, please refer line 148. 

                There is one more possibility that the test fails, If JTwork is not cleared before executing fix.

                Please try as,

1.       Run original test using jtreg => Test FAILs

2.       Make the fix  change.

3.       Delete the JTwork folder

4.       Run the test again using jtreg => Test PASSes.

If we skip the step 3, the test would fail.

Request you to try as above.

Many Thanks,

Ambarish

Hi Ambarish,

But I did not touch the mouse. 
Usually mouse events come in the next sequence MOUSE_PRESSED, MOUSE_RELEASED,MOUSE_CLICKED. Why do you think that mouseClicked()->mousePressed() replacement should change something in the test?

Dear  Semyon,

                This test uses the mouse for input.

                While the test is running with or without fix, mouse should not be disturbed.

                                ------------------------------

guess we should not touch mouse while test in in progress, in that case it passed.
Fix looks fine to me.

Prasanta

-----------------------------

                Prasanta also has verified similar way, that the test passes.

                Kindly request you to try again.

                Also If possible, please share the execution log of failure for me to verify.

Many Thanks,

Ambarish

Hi Ambarish,

After your fix applying the test still fails.

Dear All,

                Kindly review the fix for JDK9.

                Bug: https://bugs.openjdk.java.net/browse/JDK-8048171

                Webrev: http://cr.openjdk.java.net/~rchamyal/ambarish/8048171/webrev.00/

Issue:

                This is an Opaque overlapping test for each AWT component.

                To test this functionality, a MouseAdapter is registered as mouseListener with overridden mouseClicked() .

                Test fails, due to issue with Event on Linux/Solaris, that mouseClicked event is not generated correctly to Choice.

Fix:

                This is an overlapping test and not a test for mouseCicked() for Choice.

                The test simulates mouseClick event by sequentially passing mousePress & mouseRelease events.

                Overriding mousePressed() instead of mouseClicked() for the registered mouse adapter solves the issue,

without causing any side effect in test execution on Windows.

Fix Verification:

                Verified successful execution of below tests using jtreg,

                java/awt/Mixing/AWT_Mixing/OpaqueOverlapping.java

java/awt/Mixing/AWT_Mixing/OpaqueOverlappingChoice.java

Many Thanks,

Ambarish Rapte
