RFR: 8343601: javax/swing/JMenuItem/8158566/CloseOnMouseClickPropertyTest.java fails in ubuntu 22.04 [v4]

[Prasanta Sadhukhan]

> It is seen that javax/swing/JMenuItem/8158566/CloseOnMouseClickPropertyTest.java fails in ubuntu 22.04 OCI instance. It is seen that test frame is being rendered at top-left of screen instead of at the center, and robot mouseMove is being used to point and click on radiobutton, checkbox etc and linux left dock placement can be a problem with this top-left rendering.
> 
> Fix is made to render the frame at the center.
> Repeated iteration of the test run in 22.04 OCI instance is ok.
