| * @summary converted from VM Testbase nsk/jdwp/ObjectReference/MonitorInfo/monitorinfo001. |
| * VM Testbase keywords: [quick, jpda, jdwp] |
| * VM Testbase readme: |
| * DESCRIPTION |
| * This test performs checking for |
| * command set: ObjectReference |
| * command: MonitorInfo |
| * Test checks that debugee accept the command packet and |
| * replies with correct reply packet. |
| * Also test checks that expected threadIDs returned either for |
| * monitor owner and waiter threads. |
| * Test consists of two compoments: |
| * debugger: monitorinfo001 |
| * debuggee: monitorinfo001a |
| * First, debugger uses nsk.share support classes to launch debuggee |
| * and obtain Transport object, that represents JDWP transport channel. |
| * Also communication channel (IOPipe) is established between |
| * debugger and debuggee to exchange with synchronization signals. |
| * Debuggee created oan object of the tested class as value of the class |
| * static field and starts several threads, which are waiting for this |
| * object monitor, and one thread, which ownes the object monitor. |
| * Then debuggee sends signal READY to the debugger. |
| * Debugger obtains from debuggee classID for tested class and objectID |
| * as the value of the class static field. Also debugger obtains threadIDs |
| * for all tested thread into debuggee. |
| * Debugger suspends debuggee (and all threads into it) before sending |
| * tested JDWP command. |
| * Then, debugger creates command packet for ObjectReference.MonitorInfo |
| * command with the found objectID as an argument, writes packet to |
| * the transport channel, and waits for a reply packet. |
| * When reply packet is received, debugger parses the packet structure |
| * and extracts threadIDs of thread waiting and owning the object monitor. |
| * Debugger checks that extracted threadIDs are equals to the expected ones.. |
| * Finally, debugger resumes debuggee, sends it signal to quit, waits |
| * for it exits and exits too with the proper exit code. |
| * COMMENTS |
| * For JDK 1.4.0-beta3 (build 1.4.0-beta3-b84) and earlier this test passed |
| * because target VM does not support VM capability: canGetMonitorInfo |
| * Test was fixed due to test bug: |
| * 4864492 TEST_BUG: potential race in JDWP test monitorinfo001 |
