 * DESCRIPTION
 *     This JVMTI test exercises JVMTI event ClassFileLoadHook().
 *     This test checks if CLASS_FILE_LOAD_HOOK event with expected
 *     bytecode and classloader is received upon loading of tested class.
 *     The tested class is loaded with custom classloader.
 *     The test performs the following checks:
 *         - CLASS_FILE_LOAD_HOOK event callback is invoked and only once
 *           for the tested class upon its loading
 *         - redefined class reference passed to callback for tested class
 *           is NULL
 *         - classloader reference passed to callback for tested class
 *           is not NULL
 *         - classloader reference passed to callback for tested class
 *           is equal to expected classloader
 *         - original bytecode passed to callback for tested class
 *           is equal to expected one
 *     The debuggee class preliminary loads original bytecode of the
 *     tested class as a byte array into static field and agent gets
 *     this bytecode and then compares it with bytecode received with
 *     tested event.
 *     If all checks are successfull the test passes with exit code 95,
 *     otherwise the test fails with exit code 97.
 * COMMENTS
 *     Modified due to fix of the rfe
 *     5010823 TEST_RFE: some JVMTI tests use the replaced capability
