// Clarification on @requires declarations:

// CDS is not supported w/o the use of Compressed OOPs

// JVMTI's ClassFileLoadHook is not supported under minimal VM

// This test class uses TransformRelatedClasses to do its work.

// The goal of this test is to exercise transformation of related superclass

// and subclass in combination with CDS.

// The transformation is done via ClassFileLoadHook mechanism.

// Both superclass and subclass reside in the shared archive.

// The test consists of 4 test cases where transformation is applied

// to a parent and child in combinatorial manner.

// Please see TransformRelatedClasses.java for details.
