A DESCRIPTION OF THE PROBLEM :
jdk.internal.misc.Unsafe implements methods to read/write native memory in following fashion:
@ForceInline
public byte getByte(long address) {
return getByte(null, address);
}
As can be seen, a null value is passed on the stack without a reason.
To resolve this, the method should be defined as:
@HotSpotIntrinsicCandidate
public native byte getByte(long offset);
The reason to resolve this is because the current implementation is slower than the older one in eg. Java 8.
