      Description



      Name: laC46010 Date: 01/23/97


      The test below shows that CallBooleanMethodA incorrectly passes
      argument values of types short, byte, char and float.

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

      > jnirun
      wrong short argument value:-251727040, should be -3842
      wrong byte argument value:-1711279272, should be -103
      wrong char argument value:, should be ?
      wrong float argument value:5.2336777E+13, should be 99.9
