 * @summary converted from VM Testbase nsk/jdwp/Event/CLASS_PREPARE/clsprepare001.
 * VM Testbase keywords: [quick, jpda, jdwp]
 * VM Testbase readme:
 * DESCRIPTION
 *     This test performs checking for
 *         command set: Event
 *         command: Composite
 *         command set: EventRequest
 *         command: Set, Clear
 *         event kind: CLASS_PREPARE
 *     Test checks that
 *         1) debuggee successfully creates CLASS_PREPARE event request
 *            for tested class name
 *         2) expected CLASS_PREPARE event is received when this class
 *            is loaded at the debuggee's startup.
 *         3) debuggee successfully removes event request
 *     Test consists of two compoments:
 *         debugger: thrstart001
 *         debuggee: thrstart001a
 *     First, debugger uses nsk.share support classes to launch debuggee,
 *     and obtains Transport object, that represents JDWP transport channel.
 *     Next, debugger makes CLASS_PREPARE event request for tested class
 *     and resumes debuggee to permit it to load classes.
 *     When expected CLASS_PREPARE event is received debugger checks
 *     if this event is for tested class and has correct attributes.
 *     Then debugger removes event request.
 *     Finally, debugger disconnects debuggee, waits for it exited
 *     and exits too with proper exit code.
 * COMMENTS
 *     Test was fixed due to test bug:
 *     4797978 TEST_BUG: potential race condition in a number of JDWP tests
