    Description

      JLS section 8.8.9 documents that if a class does not declare at least one constructor, the compiler will generate a constructor by default. While this policy may be convenient, for formal classes it is a poor programming practice, if for no other reason that the default constructor will have no javadoc.

      Use of a default constructor may be a reasonable javac lint warning.
