• invalid tag names
• incomplete tag descriptions
• duplicated tags
• missing Javadoc descriptions

Example:

  /**
   * Invalid tag name
   * @poram param description
   */
  public void sample(int param){
  }

Example:

  /**
   * Pointing to itself {@link #sample(int)}
   */
  public void sample(int param){
  }

Quick-fix adds the unknown Javadoc tag to the list of user defined additional tags.
