Hi Edward,

Thanks a lot for the fixing work! However, I am not so sure about the change to debug.hpp. Is the point of the Static assert thing not The missing Specialization? In which case the compile error you saw there was a static assert firing... I may be wrong, maybe Erik could clarify? Otherwise the change looks good. Thank you.

Yes, of course, I see the purpose of the STATIC_ASSERT now. Kind of obvious from the name.

The failure is in

template <DecoratorSet decorators, typename T> static void verify_types(){ // If this fails to compile, then you have sent in something that is // not recognized as a valid primitive type to a primitive Access function. STATIC_ASSERT((HasDecorator<decorators, INTERNAL_VALUE_IS_OOP>::value || // oops have already been validated (IsPointer::value || IsIntegral::value) || IsFloatingPoint::value)); // not allowed primitive type }

and the error is

/home/ed/openjdk/hs/src/hotspot/share/oops/access.inline.hpp: In instantiation of ‘void AccessInternal::verify_types() [with long unsigned int decorators = 4096; T = volatile oop]’:

I will continue too look at this but would appreciate some help.

Thanks, Ed.
