Hi Justin,

A few comments on a quick pass through your changes

test/jdk/java/util/Formatter/Basic.java line 93:

Perhaps use System.out.printf vs println and "fail" should not be needed as all tests passed

test/jdk/java/util/Formatter/BasicTestLauncher.java line 52:

You could use a DataProvider

test/jdk/java/util/Formatter/BasicTestLauncher.java line 99:

Do you need to catch the RuntimeException and then throw a new RuntimeException?  I think you might want to consider reworking this
