This number is specified + * in "-threadCount" option. Auxiliary threads begin a recursion until they + * reach specified depth ("-depth" option). Each thread may use pure java + * and/or native methods based on "-invocationType" option. Then the threads + * wait until they get a notification from main thread. So, those auxiliary + * threads are definitly in "running" state when main thread performs their + * checks. + * Main thread makes a snapshot of stack trace for all threads and checks it: + * 1. If a thread is alive, ThreadMonitor.getThreadInfo(long, -1) must + * return not null ThreadInfo. + * 2. The length of a trace must not be greater than (depth + 3). Number + * of recursionJava() or recursionNative() methods must not be greater + * than depth, also one Object.wait() or Thread.yield() method, one + * run(), and one waitForSign(). + * 3. The latest method of the stack trace must be RunningThread.run(). + * 4. getClassName() and getMethodName() methods must return expected + * values for each element of the stack trace. + * If one of that testcases fail, the test also fails. + * After all threads are checked, main thread notifies them to complete their + * job. Then the test repeats the procedure with starting threads and + * performing checks ITERATIONS times. + * This particular test performs access to the MBeans' methods through custom + * MBeanServer and uses pure java methods in auxiliary threads. + * COMMENTS + * + * @library /vmTestbase + * /test/lib + * @run driver jdk.test.lib.FileInstaller . . + * @run main/othervm/native + * nsk.monitoring.stress.thread.strace001 + * -testMode=server + * -MBeanServer=custom + * -threadCount=50 + * -depth=200 + */ +
