I dont see this test failing in our CI systems "frequently"...last time it failed is June8 on a CI system which had some history of config issue, and that too on jdk17 binary and not on mainline..before that it fails on June1 due to some infra issue on mainline..and before that on June19 2021 on jdk11 binary again due to infra issue..so I dont think it's worth tinkering as of now..

also, the test has some quirks as I see. press() method is never called...it uses internal SwingTest class to start the test which I am not sure is needed
