<Swing Dev> RFR: 8199079: Test javax/swing/UIDefaults/6302464/bug6302464.java is unstable [v2]

[Prasanta Sadhukhan]

> This test was marked as unstable in CI run in samevm mode but later on was found passing in now-default othervm mode but was problemlisted only on macos by JDK-8254976.
> It is found that this test started failing in macos due to JDK-8220150:  [macos] macos10.14 Mojave returns anti-aliased glyphs instead of aliased B&W glyphs
> which turns Antialias hint even if it is set to off from macosx10.14 onwards.
> So, this test started failing when it tries to test Antialias OFF hint.
> 
> Proposed fix is to check for macosx 10.14 and greater version and bail out from this subtest.
> 
> @prrace Can you please take a look?
