      Description

        In some native data structures of the VM oops are stored uncompressed even if compressed oops are turned on, for example Klass::_java_mirror. Java code which is tightly coupled with the VM should have the ability to read and write such fields.

        This additional Unsafe API make the implementation of JEP 243: Java-Level JVM Compiler Interface simpler.
