| * @summary converted from VM Testbase nsk/jdi/ModificationWatchpointEvent/valueToBe/valuetobe002. |
| * VM Testbase keywords: [jpda, jdi] |
| * VM Testbase readme: |
| * DESCRIPTION |
| * This test exercises |
| * com.sun.jdi.event.ModificationWatchpointEvent.valueToBe() method. |
| * The test checks the following assertion: |
| * If any field of loaded class of target VM is assigned to new value |
| * which is equal to previous value, then Value reference returned |
| * by ModificationWatchpointEvent.valueToBe() is equal to one |
| * returned by Watchpoint.valueCurrent(). |
| * A debugger class - nsk.jdi.ModificationWatchpointEvent.valueToBe.valuetobe001 ; |
| * a debuggee class - nsk.jdi.ModificationWatchpointEvent.valueToBe.valuetobe001a . |
| * The test uses supporting nsk/jdi/share classes for launching debuggee |
| * and for creating communication pipe between debugger and debuggee. The |
| * debugger and debugee communicates with special commands. |
| * The debugger creates ModificationWatchpointRequests to the fields defined |
| * in debuggee class. |
| * The debugger starts <Eventhandler> thread for listening events delivered |
| * from debuggee. |
| * Upon receiving <GO> command from debugger, the debuggee assignes every field |
| * to itself (i.e. the old and new values of the field are equal) and sends |
| * command <DONE>. |
| * The debugger switches to <EventHandler> to listen the event during the |
| * time specified by <waittime> parameter. Then debugger shuts down debuggee |
| * by <QUIT> command. |
| * If debugger receives ModificationWatchpointEvent, it compares old and new |
| * values of field referenced in the event. The test fails if any of this |
| * these values are not equal. The test also fails if no |
| * ModificationWatchpointEvent was received. |
| * COMMENTS |
| * Test fixed due to bug: |
| * 4455653 VMDisconnectedException on resume |
| * ---------- |
| * I. To fix the bug 4505870, the following is done in file valuetobe001a.java: |
| * - assignments values to the fields lS0, lP0, lU0, lR0, lT0, and lV0 |
| * are added (new lines 153-158). |
| * II. Several improvments: |
| * debugger: |
| * - line 129: check value is in requestsCount; |
| * - old line 37 removed; |
| * - check for all expected events received (lines 233-248) removed. |
| * debuggee: |
| * - line 25 removed. |
| * ---------- |
| * Standard method Debugee.endDebugee() is used instead of cleaning event queue on debuggee VM exit. |
