JVMPI - Profiler requested something 00C02C68 that isn't an
object

I am working on a java profiler and found this issue when calling JRocket 1.5.0*
JVMPI API.

JavaCoreBindings::objectId_t obj = g_jvmpi_iface->GetThreadObject(m_envId);

and the error happens after requesting the event.

int result = g_jvmpi_iface->RequestEvent 
                                (JVMPI_EVENT_THREAD_START, obj);

error:
JVMPI - Profiler requested something 00C02C68 that isn't an object.

But it works fine with SUN jdk. Any idea would be really helpful to us.
