      Description

        The assertion was hit in JavaThread::pd_get_top_frame_for_profiling (after JDK-8290004 was fixed) while testing jdk/jfr/api/consumer/log/TestSystemEvents.java.

        The acquire barrier from JDK-8290004 has helped, but not fixed all problems. "last_Java_pc" can still be observed as 0 in rare cases because not all writers use a release barrier.
