                    throws IllegalClassFormatException

A method to delegate to when the module system is supported on the current JVM.

Parameters:

rawModule - The instrumented class's java.lang.Module.

classLoader - The type's class loader or null if the type is loaded by the bootstrap loader.

internalName - The internal name of the instrumented class.

classBeingRedefined - The loaded Class being redefined or null if no such class exists.

protectionDomain - The instrumented type's protection domain or null if not available.

binaryRepresentation - The class file of the instrumented class in its current state.

Returns:

The binary representation of the transformed class file or null if no transformation should be applied.

Throws:

IllegalClassFormatException - If the class file was found invalid.

 @MaybeNull
 Class<?> classBeingRedefined,
 @MaybeNull
 ProtectionDomain protectionDomain,
 byte[] binaryRepresentation)
                      throws IllegalClassFormatException

Callback between the transformation callbacks.

Parameters:

rawModule - The instrumented class's java.lang.Module.

classLoader - The type's class loader or null if the type is loaded by the bootstrap loader.

internalName - The internal name of the instrumented class.

classBeingRedefined - The loaded Class being redefined or null if no such class exists.

protectionDomain - The instrumented type's protection domain or null if not available.

binaryRepresentation - The class file of the instrumented class in its current state.

Returns:

The binary representation of the transformed class file or null if no transformation should be applied.

Throws:

IllegalClassFormatException - If the class file was found invalid.
