 * @test
 *
 * @summary converted from VM Testbase nsk/jdb/down/down002.
 * VM Testbase keywords: [jpda, jdb]
 * VM Testbase readme:
 * DECSRIPTION
 *  This tests the jdb 'down' command. The test sets a breakpoint
 *  at 'func5' method in debugged 'nsk.jdb.down.down002a' class and then
 *  runs the debugee.  Once, an execution suspends at 'func5' method,
 *  the 'down' command is issued to the debugger several times.
 *  The output is processed by counting the number of times
 *  each method name appears in the stack trace. The test passes
 *  if the obtained count matches the expected one.
 * COMMENTS
 *  This test functionally equals to nsk/jdb/down/down001 test and
 *  replaces it.
 *
