| * @summary converted from VM Testbase nsk/jdb/interrupt/interrupt001. |
| * VM Testbase keywords: [jpda, jdb] |
| * VM Testbase readme: |
| * DECSRIPTION |
| * A positive test case for the 'interrupt <thread id>' command. |
| * The debuggee program (interrupt001a.java) creates a number of additional |
| * threads with name like "MyThread-<number>" and starts them. The jdb |
| * suspends the debuggee at a moment when the additional threads are |
| * waiting for notification for lock objects and then tries to interrupt them. |
| * If these threads are interrupted then a value of the special |
| * "notInterrupted" variable should not be modified. |
| * Value of "notInterrupted" variable is checked by "eval <expr>" command. |
| * The test passes if the value is equal to 0 and fails otherwise.. |
| * COMMENTS |
| * Modified due to fix of the bug: |
| * 4760826 TTY: 'interrupt <threadID>' command sometimes does not work in Mantis |
| * Modified due to fix of the bug: |
| * 4974992 Missed prompt with jdb testcase nsk/jdb/interrupt/interrupt001 |
