      The assertion failure arises under the run of
      /net/sqesvr/vsn/testbase/testbase_nsk/src/nsk/arguments/sysdic00101 test
      using java_g (java version "1.2.2"
      Java HotSpot(TM) Server VM (2.0merlin, mixed mode, debug build A)).
      This assertion failure reproduces under the run through Tonga.
      Need to note, sysdic00101 test has stutus "PASS" after the run.
      This failure does not reproduce without Tonga using.
      See log below.
