    Description copied from class: OpcodeStackDetector
    
    By default, this method will not be called when stack is TOP. To change this behavior, override #beforeOpcode(int) and change to return true even if stack is TOP.
    
    see Using FindBugs for Research to learn lattice and what TOP means.
