| * |
| * @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. |
