/*
 * @test
 *
 * @summary converted from VM Testbase nsk/jdb/stop_in/stop_in002.
 * VM Testbase keywords: [jpda, jdb]
 * VM Testbase readme:
 * DESCRIPTION
 *  This is a test for the jdb "stop at <class:line>" command.
 *  The test driver sets three breakpoints in debugged 'stop_in002b'
 *  class:
 *   - in static initilizer,
 *   - in constructor,
 *   - in a method of static nested class,
 *   - in a method of instance nested class,
 *   - in final method.
 *  The test passes if the debuggee is suspended at every breakpoint
 *  had been set and "Breakpoint hit" message had been printed in
 *  jdb's output stream.
 *  The test consists of:
 *   nsk.jdb.stop_in.stop_in002.java - test driver,
 *   nsk.jdb.stop_in.stop_in002a.java - debugged application.
 * COMMENTS
 *  This test functionally covers nsk/jdb/stop_in/stop_in001 test
 *  and replaces it.
 *
