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

This line is missing a newline; add a \n, or use println().

test/jdk/java/util/Formatter/BasicTestLauncher.java line 35:

For the record, I've not deduced how/why the rest of the .java files in the test get compiled to .class files...

test/jdk/java/util/Formatter/BasicTestLauncher.java line 47:

IMO it's not necessary to create constants if they'll only be used as a ValueSource

test/jdk/java/util/Formatter/BasicTestLauncher.java line 49:

A name like "JAVA_OPTS" would better express how this value is used.

test/jdk/java/util/Formatter/BasicTestLauncher.java line 51:

This is the name of a compiled class to be run, not a source file, so perhaps, "TEST_CLASS"?
