| * @summary converted from VM Testbase nsk/jdi/ThreadStartEvent/thread/thread001. |
| * VM Testbase keywords: [jpda, jdi] |
| * VM Testbase readme: |
| * DESCRIPTION |
| * The test exercises |
| * com.sun.jdi.event.ThreadStartEvent.thread() method. |
| * The test checks the following assertions: |
| * - ThreadStartEvent is always received by debugger |
| * for all started threads in target VM, |
| * - ThreadStartEvent.thread() returns valid ThreadReference |
| * to expected thread in target VM, |
| * - ThreadStartEvent is received only once for each expected thread |
| * A debugger class - nsk.jdi.ThreadStartEvent.thread.thread001 ; |
| * a debuggee class - nsk.jdi.ThreadStartEvent.thread.thread001a . |
| * 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 and enables ThreadStartRequest. |
| * The debuggee creates two auxiliary checked threads: <Thread1>, <Thread2>. |
| * Before starting threads, debuggee's main thread locks special |
| * synchronized object <lock> to prevent auxiliary threads from finishing |
| * before test checks performed. |
| * The debugger starts special thread <EventHandler> for listening events |
| * received from debuggee, and resumes debuggee.The <EventHandler> expects |
| * ThreadStartEvent for each debuggee threads, including main thread, and |
| * marks that thread in <checkedThreads> array. |
| * For each received ThreadStartEvent it is verified to refer to the |
| * right request, VM, thread references. |
| * Debugger waits for <EventHandler> receives all expected events |
| * for WAITTIME timeout. If not all events have been received, |
| * debugger complains about an error. |
| * Finally, debugger disables event request, cleans events queue, |
| * sends debuggee command <QUIT>, waits for debuggee terminated, |
| * and exits. |
| * The test fails if any of the checks failed. |
| * COMMENTS |
| * Test fixed due to bugs: |
| * 4455653 VMDisconnectedException on resume |
| * 4463674 TEST_BUG: some JDI tests are timing dependent |
| * ------------------------------------------------------------- |
| * Modified to fix the bug 4501953, |
| * the file thread001a.java is modified as follows. |
| * - A special waitnotify Object is added in the class thread001a. |
| * - In classes InnerThread and OuterThread, |
| * synchronized blocks are added |
| * to make newly created thread certainly to run. |
| * - In the class thread001a, |
| * the pervious mechanizm of waiting for predefined time |
| * is replaced with new one based on wait-notify. |
| * ------------------------------------------------------------- |
| * 4434432 TEST_BUG: ThreadStartEvent does not received on Linux |
| * ------------------------------------------------------------- |
| * Standard method Debugee.endDebugee() is used instead of cleaning |
| * event queue on debuggee VM exit. |
