/**
 * This abstract class provides a basic implementation of the functionalities that should be provided
 * by any formatter used by javac. Among the main features provided by AbstractDiagnosticFormatter are:
 *
 * <ul>
 *  <li> Provides a standard implementation of the visitor-like methods defined in the interface DiagnisticFormatter.
 *  Those implementations are specifically targeting JCDiagnostic objects.
 *  <li> Provides basic support for i18n and a method for executing all locale-dependent conversions
 *  <li> Provides the formatting logic for rendering the arguments of a JCDiagnostic object.
 * </ul>
 *
 * <p><b>This is NOT part of any supported API.
 * If you write code that depends on this, you do so at your own risk.
 * This code and its internal interfaces are subject to change or
 * deletion without notice.</b>

     * output). Also detects cycles in wildcard messages (e.g. if the wildcard
     * type referred by a given captured type C contains C itself) which might
     * lead to infinite loops.
