+ * @test
+ *
+ * @summary converted from VM Testbase nsk/jdb/pop/pop001.
+ * VM Testbase keywords: [jpda, jdb]
+ * VM Testbase readme:
+ * DESCRIPTION
+ * A positive test case for the 'pop' command.
+ * The debugged application (pop001a.java) starts additional thread of MyThread
+ * class. The 'run()' method of the this class invokes recursively a number of
+ * int methods. The jdb sets breakpoint in the last called 'func5()' method
+ * to suspend the debugged VM when all the methods, i.e. from 'func1()' to
+ * 'func5()', are in MyThread's stack. Then jdb steps up three frame on stack
+ * by 'up 3' command. At this moment frame with 'func2()' is current.
+ * Then the 'pop' command is called. The test passes if after execution of
+ * tested command the 'func1()' frame becomes current and jdb correctly reports
+ * the thread stack and local variable(s) of the current frame.
+ * The test consists of two program:
+ * pop001.java - launches jdb and debuggee, writes commands to jdb, reads the jdb output,
+ * pop001a.java - the debugged application.
+ * COMMENTS
