 * @test

 * @summary converted from VM Testbase nsk/jdb/clear/clear004.
 * VM Testbase keywords: [jpda, jdb]
 * VM Testbase readme:
 * DECSRIPTION
 *  A positive test case for the 'clear <class_id:line>' command.
 *  The test sets 3 breakpoints and then clears one after the first
 *  breakpoint is reached. The tests verifies that jdb does not
 *  halt execution at the cleared breakpoint.
 * COMMENTS
 *  This test functionally equals to nsk/jdb/clear/clear004 test and
 *  replaces it.
