<AWT Dev> RFR: 8253739: java/awt/image/MultiResolutionImage/MultiResolutionImageObserverTest.java fails

[Jayathirth D V]

Locally when i run this test i am seeing both the observers getting called and flags are updated.
I suspect this to be an issue with less timeout which we are using for verifying whether observer is getting called or
not. Also i have increased sleep time. I have increased timeout and verified in CI pipeline there is no issue.
