* javax/security/auth/Subject.java (doAsPrivileged): If acc is
null, create a new AccessControlContext.
* java/security/SecureClassLoader.java (protectionDomainCache):
new field.
(defineClass): Create a new protection domain and add it to our
cache.
* java/rmi/server/UnicastRemoteObject.java (exportObject): Call
addStub() to keep track of the stub we've exported.
(unexportObject): Call deleteStub().
* java/rmi/server/RemoteObject.java (stubs): New field.
(addStub): New method.
(deleteStub): New method.
(toStub): Rewrite.
* java/security/Permissions.java (PermissionsHash.implies):
Iterate over the collection and invoke implies() on each
element.
