I use a special wrapper, StressWrapper_suspendthrd003.java, to
execute the vmTestbase/nsk/jvmti/SuspendThread/suspendthrd003.java
test with specific options for a specific time slice (6646 seconds):

$ cat test/hotspot/jtreg/StressWrapper_suspendthrd003.java
/*
 * @test
 *
 * @requires vm.jvmti
 * @library /vmTestbase
 * /test/lib
 * @compile/timeout=270 vmTestbase/nsk/jvmti/SuspendThread/suspendthrd003.java
 * @run main/othervm/native/timeout=6946
 * -XX:+HeapDumpOnOutOfMemoryError
 * -Xmx128m
 * -agentlib:suspendthrd003=-waittime=5
 * nsk.jvmti.SuspendThread.suspendthrd003 6646
 */

Twice in the JDK22 project, this test has failed during a stress run.

Here are my notes:
