/**
 * The test for the implementation of an object of the type
 * StepRequest.
 *
 * The test checks that results of the method
 * <code>com.sun.jdi.StepRequest.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 cases to check include both a pattern that begin with '*' and
 * one that end with '*'.
 *
 * The test works as follows.
 * - The debugger
 *   - sets up StepRequest1 and restricts it using a pattern that
 *     begins with '*'
 *   - resumes the debuggee, and waits for expected StepEvent.
 * - The debuggee creates and starts a thread, thread1,
 *   which being run, invokes methods used
 *   to generate Events and to test the filters.
 * - Upon getting the events, the debugger performs checks required.
 *   Then the same is repeated for a pattern that ends with *.
