In some native data structures of the VM oops are stored uncompressed even if compressed oops are turned on, for example Klass::javamirror. 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. http://cr.openjdk.java.net/~twisti/8022853/hotspot/webrev.01/ http://cr.openjdk.java.net/~twisti/8022853/jdk/webrev.01/
