Wie verwende ich die HotSpot DTrace-Probes unter SmartOS?

nter Mac OS X kann ich die HotSpot-Tests zum Ausführen von Java-Programmen finden, indem ich Folgendes ausführ

cody.mello@ashur ~ (1) % sudo dtrace -ln 'hotspot*:::'
Password:
Invalid connection: com.apple.coresymbolicationd
   ID   PROVIDER            MODULE                          FUNCTION NAME
165084  hotspot46      libjvm.dylib _ZN13instanceKlass15initialize_implE19instanceKlassHandleP6Thread [instanceKlass::initialize_impl(instanceKlassHandle, Thread*)] class-initialization-clinit
165085  hotspot46      libjvm.dylib _ZN13instanceKlass15initialize_implE19instanceKlassHandleP6Thread [instanceKlass::initialize_impl(instanceKlassHandle, Thread*)] class-initialization-concurrent
165086  hotspot46      libjvm.dylib _ZN13instanceKlass15initialize_implE19instanceKlassHandleP6Thread [instanceKlass::initialize_impl(instanceKlassHandle, Thread*)] class-initialization-end
165087  hotspot46      libjvm.dylib _ZN13instanceKlass15initialize_implE19instanceKlassHandleP6Thread [instanceKlass::initialize_impl(instanceKlassHandle, Thread*)] class-initialization-erroneous
165088  hotspot46      libjvm.dylib _ZN13instanceKlass15initialize_implE19instanceKlassHandleP6Thread [instanceKlass::initialize_impl(instanceKlassHandle, Thread*)] class-initialization-error
165089  hotspot46      libjvm.dylib _ZN13instanceKlass15initialize_implE19instanceKlassHandleP6Thread [instanceKlass::initialize_impl(instanceKlassHandle, Thread*)] class-initialization-recursive
...

Aber wenn ich ein einfaches Java-Programm erstelle und es unter SmartOS ausführe:

cody@101901c9-6d66-ea32-fe42-f1fbebd4bf99 ~ % cat Loop.java 
class Loop {

    public static void main(String[] args) throws InterruptedException {
        while (true) {
                Thread.sleep(5000);
        }
    }
}
cody@101901c9-6d66-ea32-fe42-f1fbebd4bf99 ~ % javac Loop.java 
cody@101901c9-6d66-ea32-fe42-f1fbebd4bf99 ~ % java Loop

Ich kann keine Sonden finden:

cody@101901c9-6d66-ea32-fe42-f1fbebd4bf99 ~ (255) % pfexec dtrace -ln 'hotspot*:::'
   ID   PROVIDER            MODULE                          FUNCTION NAME
dtrace: failed to match hotspot*:::: No probe matches description

Gibt es etwas Besonderes, das ich tun muss, um sie zu sehen?
