/**
 * The test for the implementation of an object of the type
 * ClassPrepareRequest.
 *
 * The test checks that results of the method
 * <code>com.sun.jdi.ClassPrepareRequest.addClassExclusionFilter(String)</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 matches a restricted regular expression.
 * The case to check includes a pattern that begins with '*'.
 *
 * The test works as follows.
 * - The debugger
 *   - sets up a ClassPrepareRequest,
 *   - using a string pattern, restricts it with addClassExclusionFilter,
 *   - resumes the debuggee, and waits for ClassPrepareEvents.
 * - The debuggee creates and starts a thread1,
 *   whose 'run' method creates objects of ClassTypes needed
 *   to generate Events and to test the filters.
 * - Upon getting the events, the debugger performs the checks required.
