<Swing Dev> RFR: 8233561: [TESTBUG] Swing text test bug8014863.java fails on macos

[Jayathirth D V]

This issue is related to not giving permission for terminal to control things in System Preferences -> Security & privacy -> Privacy -> Accessibility.

I have verified the test in our CI and removed it from problemlist. There are small tweaks in test also.
