RFR: 8296083: javax/swing/JTree/6263446/bug6263446.java fails intermittently on a VM [v2]

[Prasanta Sadhukhan]

> Test intermittently fails in VM citing "Tree is not editing". Seems to be problem with mouse clicks not getting registered properly..
> Similar test test/jdk/javax/swing/JTable/6263446/bug6263446.java is not affected, so made the test similar to it by using same safeguard using Robot.waitForIdle() and modifying clickpoint to tree cell midpoint.
> 
> Several iterations of the test pass in the OCI VM and all other physical platforms (link in JBS)
