      Description

      The c2v_readFieldValue function uses HotSpot primitives for doing an unaligned volatile read of a short. This is not supported on AArch64. Instead, the function should unconditionally perform a volatile pre-read barrier (i.e., OrderAccess::acquire()) followed by a normal read.
