Hi Misha,

These look very clean and well organized.

- The copyright headers for all source files are incorrect. Please fix them to use right copyright headers for open code.

- Could you please add descriptions in TransformInterfaceAndImplementor.java and TransformSuperAndSubClasses.java with details explaining what do they test and what are the expected behavior/result. It would help people understand the tests by listing all the test cases. It would also be helpful to explain what part is transformed in each class. I know TransformRelatedClasses already have comments with some explanations. If you prefer, you could add more details in TransoformRelatedClasses.java and add one-line comment in TransformInterfaceAndImplementor.java & TransformSuperAndSubClasses.java referring to TransoformRelatedClasses.java.

I agree with Ioi’s suggestion about moving TransformUtil, TranformerAgeent to hotspot/testlibrary/jvmti. That way they can be used by other tests (in different location).
