Thank you for the comments.
Alex, you are right.
I've misread this code at line 201:
199 err = jvmti->SuspendThread(vthread);
200 if (err == JVMTI_ERROR_THREAD_NOT_ALIVE) {
201 continue;
202 }
203 check_jvmti_status(jni, err, "Error in SuspendThread");
204 // LOG("Agent: suspended vt: %s ct: %s\n", vname, cname);
205
206 check_vthread_consistency_suspended(jvmti, jni, vthread);
The function `check_vthread_consistency_suspended()` is not called when if the
`SuspendThread` returned `JVMTI_ERROR_THREAD_NOT_ALIVE` error code.
It does not look as a test bug then.
