RFR(M) 8212605: Pure-Java implementation of AccessController.doPrivileged

[Roger Riggs]

Hi Dean,

typo AccessController line788: "annocations"

The implementations of

doPrivileged(PrivilegedExceptionAction<T> action) and
doPrivileged(PrivilegedAction<T> action)

Could be a bit more similar since except for the exception wrapping they 
are the same.

309 return executePrivileged(action, null, Reflection.getCallerClass()); 
vs. AccessControlContext context = null;
548 Class <?> caller = Reflection.getCallerClass();
549 try {
550 return executePrivileged(action, context, caller);

The context and caller locals aren't needed.

Thanks, Roger
