      Description



      Name: laC46010 Date: 01/23/97


      The test below shows that GetStaticFieldID cannot access "itrf_fld" field
      of the class gsfi00101 which is inherited from the interface "Interf".

      To run the test, set environment variables JH (Java home) and CC (C compiler)
      and run "jnirun" script.

      ./jnirun
      GetStaticFieldID: cannot get interface field
      Exception caught: java.lang.NoSuchFieldError: itrf_fld
