// 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; each class lives in its own package.
// 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.
