public class MethodSetCheck
private class MethodComparator implements Comparator
public int compare(Object o1, Object o2)
DFE reports that "Method 'compare' is not designed for
extension". That is true, but it does not make sense.
The pupose of the DFE check is to protect against bugs
in derived classes in other packages, and private inner
classes can't be extended in such other packages.
I haven't tested this, but maybe DFE has the same
problems when checking package visible classes...
Not quite sure about the version of Checkstyle I'm
using right now, running it through Maven rc1.
