      The HotSpot Client VM (Solaris_JDK_1.3-b15, build 1.3-internal) fails the tests
      nsk/jvmdi/ClearBreakpoint/clrbrk001
      nsk/regression/b4289109
      nsk/regression/b4289162
      from
      testbase_nsk

      See comments from ###@###.###:
      "...
      For the breakpoint related tests, these are failing because we fixed
      a different bug on Solaris (where UseFastBreakpoints is enabled). I
      looked into UseFastBreakpoints on Friday before I left CA. I don't
      like what I see and I'm going to ask about disabling the feature on
      Solaris until I'm happy with it. Please file a new "fast breakpoints"
      are broken as a P3 including the following tests:

          nsk/jvmdi/ClearBreakpoint/clrbrk001
          nsk/regression/b4289109
          nsk/regression/b4289162

      Normally, I would file regressions as P2, but when UseFastBreakpoints
      is disabled, I expect these tests to pass.
      ..."

      To reproduce the bug run
      doit.ksh <jdk root directory>
      in
      /net/sqesvr/vsn/GammaBase/Bugs/<this bug number>

      The test produces the output:
