Because the JNI tests use C code, it is not possible to
define their compilation in a platform-independent way.
Therefore, you must compile and link the JNI tests before
running them within JavaTest. These files must be compiled
so they can be loaded by calling the
System.loadLibrary("jckjni") method on your
platform.
Place the library in a directory that is accessible when
you run the tests.
JNI test setup is described in detail in the "Special Test
Setup" chapter of the Java Compatibility Kit User's
Guide.
