Description
Deprecate the memory-access methods in sun.misc.Unsafe for removal in a future release. These unsupported methods have been superseded by standard APIs, namely the VarHandle API (JEP 193, JDK 9) and the Foreign Function & Memory API (JEP 454, JDK 22). We strongly encourage library developers to migrate from sun.misc.Unsafe to supported replacements, so that applications can migrate smoothly to modern JDK releases.
Comments
I've removed the release-note=yes label from this issue as a RN will be created automatically from the JEP summary.
