Tue Sep 2 07:21:34 UTC 2025

Issue:
java/awt/Focus/ComponentLostFocusTest.java fails intermittently(2/40) with an exception " Execution failed: `main' threw exception: java.lang.RuntimeException: TextField got no focus! Test failed."
I have seen it failing in all platforms, but predominantly in macos platform.
It fails sometimes in CI also.

Fix:
Added a countdownlatch for tracking focusGained
Added screenshot logic

Testing:
Tested in all mach5 platforms and got all PASS.
