/**
 * <p>This class implements unit test for RMI Bootstrap.
 * When called with no arguments main() looks in the directory indicated
 * by the "test.src" system property for files called management*ok.properties
 * or management*ko.properties. The *ok.properties files are assumed to be
 * valid Java M&M config files for which the bootstrap should succeed.
 * The *ko.properties files are assumed to be configurations for which the
 * bootstrap & connection test will fail.</p>
 *
 * <p>The rmi port number can be specified with the "rmi.port" system property.
 * If not, this test will use 12424</p>
 *
 * <p>When called with some argument, the main() will interprete its args to
 * be Java M&M configuration file names. The filenames are expected to end
 * with ok.properties or ko.properties - and are interpreted as above.</p>
 *
 * <p>Note that a limitation of the RMI registry (bug 4267864) prevent
 * this test from succeeding if more than 1 configuration is used.
 * As long as 4267864 isn't fix, this test must be called as many times
 * as needed but with a single argument (no arguments, or several arguments
 * will fail).</p>
 *
 * <p>Debug traces are logged in "sun.management.test"</p>
