Issue	Fix Version	Assignee	Priority	Status	Resolution	Resolved In Build
JDK-8280561	17.0.3-oracle	Tobias Hartmann	P3	Resolved	Fixed	b04
JDK-8281020	17.0.3	Goetz Lindenmaier	P3	Resolved	Fixed	b01

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.
