The popular header method.hpp includes vmSymbol.hpp for this inline function

  bool is_continuation_enter_intrinsic() const {
    return intrinsic_id() == vmIntrinsics::_Continuation_enterSpecial;
 }

This causes the large header files vmSymbols.hpp and vmIntrinsics.hpp to be unnecessarily included by many HotSpot object files.

The fix is to move this function to method.inline.hpp.

(It might be performance critical since it's used by some loops that walk the call frames).
