> Deprecate the sun.misc.Unsafe methods that return field offsets. These method > are an impediment to possible future changes. Layout may not be fixed in the > future, the VM should be allowed to re-layout dynamically based on patterns > of usage. We also have the issue of libraries using these methods to get > offsets (sometimes of classes with the same layout as JDK classes) so they > can directly access the fields of privileged classes. It's untenable for > libraries to rely on this going forward. > > The java.lang.invoke.VarHandle API (added in Java 9) provides a strongly > typed reference to a variable that is a safe and a much better alternative to > many cases that use these methods. Deprecating these method provides a gentle > nudge in that directory. Once the Panama memory APIs are permanent then we > can look at terminally deprecating and removing these methods, along with the > accessors.
