String comparison in GroupManager

[GoogleCodeExporter]

In GroupManager the following is used for String comparison:

                if(group == g || group.equals(g)) {
                    return true;
                }

This kind of micro-optimization isn't necessary, the jvm developers are 
perfectly aware of String interning and the implementation of String.equals 
includes:

        if (this == anObject) {
            return true;
        }
