public class ClassConstantInstruction

extends Object

Pseudo-instruction used to place Class types onto the stack. This logical instruction may actually involve a large chunk of code, and may even add static synthetic fields and methods to the owning class. Therefore, once the type of Class being loaded is set, it cannot be chanced. Also, this instruction is invalid as the target of any jump instruction or exception handler.
