- getType
  
  public Type getType(ConstantPoolGen cp)
  
  Specified by:
  
  getType in interface TypedInstruction
  
  Returns:
  
  return address type
- physicalSuccessor
  
  public InstructionHandle physicalSuccessor()
  
  Returns an InstructionHandle to the physical successor of this JsrInstruction. For this method to work, this JsrInstruction object must not be shared between multiple InstructionHandle objects! Formally, there must not be InstructionHandle objects i, j where i != j and i.getInstruction() == this == j.getInstruction().
  
  Returns:
  
  an InstructionHandle to the "next" instruction that will be executed when RETurned from a subroutine.
