 * DESCRIPTION
 *         Test covers bug 6426321. Test stress event queue forcing loading of 3000 classes in debuggee.
 *         Debugger in loop sends commad to debuggee to load class and waits READY answer.
 *         Test passes if no hangs or any other errors occur in debuggee (if debuggee successfully sends answers for all commands).
 *         (number of classes to load can be changed through parameter -classesToLoad (for example -classesToLoad 1000)).
