Class FINISHCLINIT

java.lang.Object

gov.nasa.jpf.vm.Instruction

gov.nasa.jpf.jvm.bytecode.FINISHCLINIT

All Implemented Interfaces:

Attributable, InstructionInterface, java.lang.Cloneable

public class FINISHCLINIT
extends Instruction

artificial bytecode to defer class status changes of classes that don't have a (), simulating native VM specific behavior that involves nested locking during class init

Modifier and Type	Method and Description
Instruction	execute(ThreadInfo ti) this is the real workhorse returns next instruction to enter in this thread <2do> it's unfortunate we roll every side effect into this method, because it diminishes the value of the 'executeInstruction' notification: all insns that require some sort of late binding (InvokeVirtual, GetField, ..) are not yet fully analyzable (e.g.
int	getByteCode()
boolean	isExtendedInstruction() is this one of our own, artificial insns?

execute

public Instruction execute(ThreadInfo ti)

Description copied from class: Instruction

this is the real workhorse returns next instruction to enter in this thread <2do> it's unfortunate we roll every side effect into this method, because it diminishes the value of the 'executeInstruction' notification: all insns that require some sort of late binding (InvokeVirtual, GetField, ..) are not yet fully analyzable (e.g. the callee of InvokeVirtuals is not known yet), putting the burden of duplicating the related code of enter() in the listener. It would be better if we factor this 'prepareExecution' out of enter()
