    43 // The goal of this test is to exercise transformation of related superclass
       
    44 // and subclass in combination with CDS; each class lives in its own package.
       
    45 // The transformation is done via ClassFileLoadHook mechanism.

    47 // The test consists of 4 test cases where transformation is applied
       
    48 // to a parent and child in combinatorial manner.
