  Method and Description
  org.apache.commons.configuration2.ImmutableConfiguration.getArray(Class<?>, String, Object) This method should not be used any more because its signature does not allow type-safe invocations; use `ImmutableConfiguration.get(Class, String, Object)` instead which offers the same functionality; for instance, to query for an array of ints use `int[] result = config.get(int[].class, "myArrayKey", someDefault);`.
  org.apache.commons.configuration2.plist.SimpleCharStream.getColumn()
  org.apache.commons.configuration2.plist.SimpleCharStream.getLine()
