    support for line-Breakpoints

    instances of me are created when line-breakpoints are placed.
    The only function I serve is to provide the originalMethod information,
    and an easy way to check for having a breakpoint (is breakpointed).

    Caveat:
        very stupid - had to repead the definition from MethodWithBreakpoints.
        Probably it is a stupid idea, to implement breakpointed methods this way (by inheritance),
        instead of having some attribute in the method (such as in an annotation).
        May someone change that?...
