[jdk25u] RFR: 8355478: DoubleActionESC.java fails intermittently

[Trupti Patil]

- PR Changes
The test currently uses a CountDownLatch of 1, causing it to validate too early—after only one open/close interaction—making the result unreliable. Setting the latch to 2 ensures both ESC-triggered open-close cycles complete before validation, aligning the test with its intended behavior.

- Testing
Test passes on windows and macos. Test is problemlisted for linux due to [JDK-8356981](https://bugs.openjdk.org/browse/JDK-8356981).

- Conflicts
No conflicts. Clean backport.

- Are higher backports completed(25u,21u,17u,11u,8u etc) ? 
Applicable to 25u via this MR and the others are being worked upon.

- Does it contain multiple changesets ?
No
