the signature of method is public final <C> IConverter<C>
getConverter(Class<C> clazz) ;
public IConverter<String> getConverter(Class<String> type)
^^ means not overriding correctly as method signature is not the same
public <String> IConverter<String>getConverter(Class<String> type)
now you have declared <String> as your type parameter but you will
not be able to use String as class in method now as the
declared <String> will now hide the String java data type..
martin has already told you the way,currently casting appears to be
the only way..
