Tested with JDK 8u151, and found the same failure in Wayland, and passed in XOrg. Since Ubuntu 17.10 uses Wayland by default, which is not supported by Java, the workaround is to use XOrg.

Looks like there are issues with Wayland, which is the default UI renderer for Ubuntu 17.10. Workaround is to use XOrg, on which this test passes. Instructions on how to switch to XOrg are provided here: https://itsfoss.com/switch-xorg-wayland/

Hi Tony, Did you test this on a VM or a standalone machine? If on VM, could you try with a standalone machine as well? Thanks, Krishna

Tried with JDK10 on ubuntu 16.04 on a standalone machine, and this test passed without any problems, so I suspect, it is something to do with Gnome desktop introduced in ubuntu 17.10.

Tried with JDK9.0.1 on ubuntu 17.10, and observed the same behavior as JDK10. [~vdyakov] : to answer your question, this test is present in JCK 9 as well, and is not passing on ubuntu 17.10.

Looks like the mouseMove in robot is not working as expected. Also, getPixelColor of robot is yielding wrong values from the native side.

is this tck-red a regression?

while I double checked today, this is not seen on OEL6.7. with OpenJDK builds 10b24, 10b36 etc. it looks to me the issue is specific to Ubuntu only.
