Some coding standards prohibit the use of clone(), and recommend using a copy constructor or a static factory method instead.

The inspection ignores calls to clone() on arrays because it's a correct and compact way to copy an array.

Example:

  class Copy implements Cloneable /*warning*/ {

    public Copy clone() /*warning*/ {
      try {
        return (Copy) super.clone(); // warning
      } catch (CloneNotSupportedException e) {
        throw new AssertionError();
      }
    }
  }
