286N/A * Basic unit test for Instrumentation appendToBootstrapClassLoaderSearch and
286N/A * appendToSystemClassLoaderSearch methods:
286N/A *
286N/A * 1. Adds a jar file to the bootstrap class loader search; Loads a class known
286N/A * to be in the jar file and checks that it was loaded by the bootstrap class
286N/A * loader.
286N/A *
286N/A * 2. Adds a jar file to the system class loader search; Loads a class known
286N/A * to be in the jar file and checks that it was indeed loaded by the system
286N/A * class loader.
