RFR: 8356061: [macos] com/apple/laf/RootPane/RootPaneDefaultButtonTest.java test fails on macosx-aarch64 machine

[Jeremy Wood]

Unfortunately I'm unable to reproduce this failure. I slowed the test down; it passes on my machine before and after this PR.

I added a little bit of logging that might also help identify what's happening.

Does anyone have any more suggestions?
