Mouse moving slow when executing tests with OpenJDK17 [message #1848570]

Hi,

We have recently switched from Java8 to OpenJDK17. In doing so we initially had some problems starting the AUT. Problems which are resloved see thread: https://www.eclipse.org/forums/index.php/t/1109511/

We have now encountered another problem which is that the mouse moves very slow when executing tests with OpenJDK17. My estimate is that it is moving at one tenth of the speed it used to.

When I switched back to Java 8 and Java 11 the mouse moves as it always have.

No other change except the one described below in the bat-script starting our application:

"C:/dev/tools/jdk/jdk-17/bin/java.exe" %DEFAULT_JVM_OPTS% %JAVA_OPTS%   com.example.ComponentMain name=com.example.release.components.gui

"C:/dev/tools/jdk/jdk-11.0.2/bin/java.exe" %DEFAULT_JVM_OPTS% %JAVA_OPTS%   com.example.ComponentMain name=com.example.release.components.gui

Anyone know how to resolve the problem?

Kind regards,
Martin

Hi again,

Upon further testing i have found that the mouse is moving slow with both Jubula ITE and Jubula client API.

Kind regards,
Martin

Have been testing some more to see if I can solve this problem.

In the ITE I can set an environment variable to disable mouse movement like this: TEST_DISABLE_MOUSE_MOVEMENT=true

When doing so the mouse doesn't move at all and the tests executes at normal speed.

This serves as a workaround while trying to get the mouse to speed up.

Anybody got a clue why the mouse is moving slow when I change Java-versions?
Could it be a Jubula thing or is Java17 behaving in a different way?

Kind regards,
Martin J

We had this problem in the past, it is mostly a thing between Java and the OS. I assume that some synchronizing we do ist now slower. But that is not every time reproducable.
If the workaround works, this ist the best way at this moment, because fixing this issue might take time.

best regards

Hello Team,
I am working on adopting the Jubula for our Product's automation.
I too have concern related this issue.
For my system, when I have jdk-11.0.10, the Tests run smoothly.
However When we change it to jdk-11.0.13, the test run extremely slow.
Switching back to jdk-11.0.10 resolves the issue

Do we have any foresight about this issue ?
This is critical for the adaptability of Jubula in Our Project.

we are currently experiencing this, too

Our story goes as follows:

Current Setup is:
- Jubula 8.7.1 with embedded jre (8.x)
- Eclipse RCP Product with integrated rc.jar running with Java 11

We are coming from Eclipse RCP running in Java 8, performed an update to running it in Java 11. Our Product runs fine in Java 11 now.

We also tested the AUT-Setup with Java 11 ... but we tested with an older version (build 11.0.9+7-LTS)

Now we switched to an updated Java 11 (build 11.0.12+8-LTS-237) and started to experience slow mouse movements.

Yesterday i found this post here (thank you for posting the question and all replies, btw!) and today we performed checks with the mentioned versions of Java 11 and we can confirm the mentioned results:

Mouse movement normal-ish with Java 11 (build 11.0.10+8-LTS-162)
Mouse movement slow with Java 11 (build 11.0.12+8-LTS-237)
Mouse movement slow with Java 11 (build 11.0.15.1+2-LTS-10)

We have not yet tested with Java 17 (but the title of this thread does not instill hope in having a fix with java 17)

- Would updating to Jubula 8.8 help?
- Would setting some Jubula Environment Variables help?

Are you already informed about the described experienced behaviour? How should we proceed?

I do not feel good vibes when having to rely on an outdated older update-version of java 11 which will deviate more and more from our productive java version.

Neither i would want to stay on Java11 u10 for our Product ¯\_(ツ)_/¯

any thoughts/comments/suggestions are welcome! (I will return after having checked how java17 performs ... or how temurin fares. Happiness ensues...

cheers
Daniel

[removed content of 2nd post, as it did not work out as expected]

P.S.: I already posted this message ... but it somehow does not show up when you open the thread ... this is my way of trying to fix that :(

You need to click on the Arrow in the last Column "Last Message" to be able to see my replies ... when you click on the thread, they do not show up :/

i just realized that 11.0.16 is the most current java 11.

And there is something for swt in it ( JDK-8274751 ) \o/

https://www.oracle.com/java/technologies/javase/11-0-16-bugfixes.html

... i think we are going to try that out next. who knows, maybe/hopefully this loop was not only impacting drag'n drop

cheers
