> If doAs() catches a PrivilegedActionException it extracts the underlying
> cause through getCause and then re-throws an exception based on the class of
> the Cause. If getCause returns null, this is how it gets re-thrown:
> else {
> throw new UndeclaredThrowableException(cause);
> }
> If cause == null that seems misleading. I have seen actual instances where
> cause is null, so this isn't just a theoretical concern.
