/**
 * The test for the implementation of an object of the type
 * ExceptionRequest.
 *
 * The test checks that results of the method
 * <code>com.sun.jdi.ExceptionRequest.addClassExclusionFilter()</code>
 * complies with its spec.
 *
 * The test checks up on the following assertion:
 *    Restricts the events generated by this request to those
 *    whose location is in a class whose name does not match a
 *    restricted regular expression.
 * The cases to check include both a pattern that begins with '*' and
 * one that end with '*'.
 *
 * The test works as follows.
 * - The debugger
 *   - sets up two ExceptionRequests,
 *   - restricts the Requests using patterns that begins with '*' and
 *     ends with *, so that, events will be filtered only from thread1,
 *   - resumes the debuggee, and
 *   - waits for expected ExceptionEvents.
 * - The debuggee creates and starts two threads, thread1 and thread2,
 *   that being run, throw NullPointerExceptions used
 *   to generate Events and to test the filters.
 * - Upon getting the events, the debugger performs checks required.
