 * @summary converted from VM Testbase nsk/jdb/where/where006.
 * VM Testbase keywords: [jpda, jdb]
 * VM Testbase readme:
 * DECSRIPTION
 *  A test to exercise the functionality of the 'where <thread_id>'
 *  and the 'where all' commands.
 *  The debugee creates 5 threads that are all suspended on locks
 *  that the main thread posseses. The 'where <thread_id>' command
 *  is used to get stack traces of all 5 suspended threads. The test
 *  passes if contents of the stack trace match to expected output.
 * COMMENTS
 *  This test functionally equals to nsk/jdb/where/where003 test
 *  and replaces it.
 *
