Yes, thanks. This is the correct thing to do in this case. dtrace
defines it as probe NewDirectByteBuffer-entry(void*, void*, uintptr_t);
so the cast is correct. The difference between SystemTap and dtrace are
a little subtle here. SystemTap will try to use the actual type directly
from the C/C++ definition, while dtrace will convert everything to
unsigned longs (and then encode the correct type in the .d file).

Cheers,
