        Description

        data_before() will SEGV if the methodDataOop data_size() is 0 and and the object
        is at the end of committed heap space.

        Fails rarely and inconsistently on a variety of platforms. No reliable means of reproduction.

        This bug was previosuly reported in 4509816, which was inadvertantly closed as a duplicate of a different bug.
