31  * DECSRIPTION
32  *  A positive test case for the 'clear <class_id:line>' command.
33  *  The test sets 3 breakpoints and then clears one after the first
34  *  breakpoint is reached. The tests verifies that jdb does not
35  *  halt execution at the cleared breakpoint.
36  * COMMENTS
37  *  This test functionally equals to nsk/jdb/clear/clear004 test and
38  *  replaces it.
