Hi, Manajit. 
Need of additional movement of a mouse means that we did not get all necessary events when the window occurred under the mouse. This test was created for JDK-7154048 which fixed similar issues: 
"1) The window does not receive the mouse entered event when it is created under the mouse" 

I run this test twice on jdk 8 GA and it is passed, so it seems we have a regression in jdk8/9. I suggest to investigate what is the root issue, and change the test so it will always fail for the first run (we can run twice when the mouse inside/ouside label).

On further debugging it was observed that the test case used to pass every time if the initial mouse move in the test actually happened. The test used to fail every second or further times because after the first execution using jtreg the mouse used to remain at the same location.
