The DTrace jstack action support (HotSpot jhelper.d) is currently broken on both JDK 7 and 8.

This is more complete picture:
It is broken in the jdk 7 builds: b00 - b06
It works Ok in the jdk 7 builds: b07 - b99
It does not work in the jdk 7 updates.
It does not work in the jdk 8.
It works Ok in the jdk 6 updates: 01-24
It does not work in the jdk 6 update 24 and later.



It worked fine for JDK 7 build 99 (for instance, look at the dtst2.method* methods in the jstack output):
