Bad practice - Class names shouldn't shadow simple name of superclass

findbugs : NM_SAME_SIMPLE_NAME_AS_SUPERCLASS

This class has a simple name that is identical to that of its superclass, except that its superclass is in a different package (e.g., alpha.Foo extends beta.Foo). This can be exceptionally confusing, create lots of situations in which you have to look at import statements to resolve references and creates many opportunities to accidently define methods that do not override methods in their superclasses.
