Looks good.

test/jdk/java/lang/constant/CondyDescTest.java line 211:

The tool swapped the lines unnecessarily.
And a couple more cases below.

test/jdk/java/lang/constant/MethodHandleDescTest.java line 113:

> 111:         testMethodHandleDesc(r);

> 113:         assertMHEquals(mh, r.resolveConstantDesc(LOOKUP));

Swapping the arguments isn't necessary since assertMHEquals is reflexive.
The method arguments don't follow the junit expected/actual ordering.
