  extended by jef.dna.instructions.impl.InstructionAncestor
      extended by jef.dna.instructions.impl.MonitorExit
All Implemented Interfaces:
java.lang.Cloneable, Instruction, BytesCountable

public class MonitorExit
extends InstructionAncestor

This class maps the MONITOREXIT bytecode instruction which exit monitor for object. The current thread should be the owner of the monitor associated with the instance referenced by objectref. If the monitor associated with objectref becomes free, other threads that are waiting to acquire that monitor are allowed to attempt to do so.
