  # need abstraction for - .reject { |name| name.in_jdk? } - have it three times
  # maybe a mixin for enumerables containing JavaTypes
  #JavaNameEnumerable with - .reject { |name| name.in_jdk? } - und anderen? reject_in_jdk = 3rd Party
  # and find_all { |n| n.same_or_subpackage_of?(x) } -- also very often  = in_package()
end

#scan_config_for_class_names(path, ignorepattern = /^\./) ⇒ Object

Find all possible class names in all XML and property files under path and optionally ignore ignorepattern
