HotSpot PermGen removal commit made

As you may know, after the takeover of Java by Oracle and the subsequent decision to merge JRockit into Hotspot, PermGen was due to be removed from Hotspot entirely. Two days ago, a commit (openjdk list message) has been made into the hotspot gc repository to remove permgen (which is the storage of class metadata) and use native memory in its place. Class metadata shall now be represented as C++ classes and will now be allocated in the metaspace linked to classloaders according to the commit message. [Source]
