Patch for TagPluginManager.java

TagPluginManager is using "Class.forName" to load extensions of TagPlugin.
It can't work when these extensions are put under the WEB-INF/lib.

Here is the code,

            String pluginClassStr = pluginClassNode.getBody();
            TagPlugin tagPlugin = null;
            try {
                Class<?> pluginClass = Class.forName(pluginClassStr);
                tagPlugin = (TagPlugin) pluginClass.newInstance();
            } catch (Exception e) {
                throw new JasperException(e);
