-/**
- * A container for all tag libraries that are defined "globally"
- * for the web application.
- *
- * Tag Libraries can be defined globally in one of two ways:
- * 1. Via <taglib> elements in web.xml:
- * the uri and location of the tag-library are specified in
- * the <taglib> element.
- * 2. Via packaged jar files that contain .tld files
- * within the META-INF directory, or some subdirectory
- * of it. The taglib is 'global' if it has the <uri>
- * element defined.
- *
- * A mapping between the taglib URI and its associated TaglibraryInfoImpl
- * is maintained in this container.
- * Actually, that's what we'd like to do. However, because of the
- * way the classes TagLibraryInfo and TagInfo have been defined,
- * it is not currently possible to share an instance of TagLibraryInfo
- * across page invocations. A bug has been submitted to the spec lead.
- * In the mean time, all we do is save the 'location' where the
- * TLD associated with a taglib URI can be found.
- *
- * When a JSP page has a taglib directive, the mappings in this container
- * are first searched (see method getLocation()).
- * If a mapping is found, then the location of the TLD is returned.
- * If no mapping is found, then the uri specified
- * in the taglib directive is to be interpreted as the location for
- * the TLD of this tag library.

+/**
+ * Specialized web application class loader.
+ * <p>
+ * This class loader is a full reimplementation of the
+ * <code>URLClassLoader</code> from the JDK. It is desinged to be fully
+ * compatible with a normal <code>URLClassLoader</code>, although its internal
+ * behavior may be completely different.
+ * <p>
+ * <strong>IMPLEMENTATION NOTE</strong> - This class loader faithfully follows
+ * the delegation model recommended in the specification. The system class
+ * loader will be queried first, then the local repositories, and only then
+ * delegation to the parent class loader will occur. This allows the web
+ * application to override any shared class except the classes from J2SE.
+ * Special handling is provided from the JAXP XML parser interfaces, the JNDI
+ * interfaces, and the classes from the servlet API, which are never loaded
+ * from the webapp repository.
+ * <p>
+ * <strong>IMPLEMENTATION NOTE</strong> - Due to limitations in Jasper
+ * compilation technology, any repository which contains classes from
+ * the servlet API will be ignored by the class loader.
+ * <p>
+ * <strong>IMPLEMENTATION NOTE</strong> - The class loader generates source
+ * URLs which include the full JAR URL when a class is loaded from a JAR file,
+ * which allows setting security permission at the class level, even when a
+ * class is contained inside a JAR.
+ * <p>
+ * <strong>IMPLEMENTATION NOTE</strong> - Local repositories are searched in
+ * the order they are added via the initial constructor and/or any subsequent
+ * calls to <code>addRepository()</code> or <code>addJar()</code>.
+ * <p>
+ * <strong>IMPLEMENTATION NOTE</strong> - No check for sealing violations or
+ * security is made unless a security manager is present.
