[Acegisecurity-developer] typo in javadoc for AbstractBasicAclEntry

[Tim Kettering]

I would think the value for (2^^1) should be (2)  not (1) as seen below?    Subclasses must indicate the permissions they support. Each base permission should be an integer with a base 2. ie: the first permission is 2^^0 (1), the second permission is 2^^1 (1), the third permission is 2^^2 (4) etc. Each base permission should be exposed by the subclass as a public static final int. It is further recommended that valid combinations of permissions are also exposed as public static final ints.
