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
