(in fact, all the assembler stepping tests).  I traced it back to this change:

2007-08-21  Sami Wagiaalla  <swagiaal@redhat.com>

        * TestFrameDebugInfo.java (testFrameDebugInfoStackTrace): New passes number
        of frames to printStackTrace.
        * DebugInfoStackFactory.java (printStackTrace): Now takes a number frames
        arguement.
