/**
 * The test for the implementation of an object of the type
 * MethodEntryRequest.
 *
 * The test checks that results of the method
 * <code>com.sun.jdi.MethodEntryRequest.addClassExclusionFilter()</code>
 * complies with its spec.
 *
 * The test checks up on the following assertion:
 *    Restricts the events generated by this request to those
 *    whose method is in a class whose name does not match
 *    this restricted regular expression. e.g. "java.*" or "*.Foo".
 * The case to checks a pattern that ends with '*'.
 *
 * The test works as follows.
 * - The debugger
 *   - sets up two MethodEntryRequests,
 *   - restricts the Requests using patterns 'java*' and 'sun*',
 *     so that events will be filtered only from test classes,
 *   - resumes the debuggee, and
 *   - waits for expected MethodEntryEvents.
 * - The debuggee creates and starts thread1, which being run,
 *   invoke methods used
 *   to generate Events and to test the filters.
 * - Upon getting the events, the debugger performs checks required.
