      Description



      Name: szC45993 Date: 03/02/99



      The Tonga/src/nsk/reflection/reflect00102 test (see sources below), which
      uses JNI, indicates HotSpot Virtual Machine Error (HotSpot VM 1.0rc1).
      Need to note that Classic VM (build JDK-1.2-V, native threads)
      and HotSpot VM (1.0beta1, mixed mode, product build) work fine (see LOG below).

      For bug demonstration, the following should be done by analogy:
