+ * 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.
+ *
