			<![CDATA[
			<p>Looks for methods that correctly do not write to a parameter. To help document this, and to perhaps

			<p>Performance gains are debatable as "the final keyword does not appear in the class file for 
			local variables and parameters, thus it cannot impact the runtime performance. It's only use

			<![CDATA[
			<p>This method uses <code>StringBuffer</code> or <code>StringBuilder</code>'s append method to concatenate strings. However, it passes the result

		<Details>
			<![CDATA[
			<p>This method uses concrete classes for parameters when only methods defined in an implemented
			interface or super class are used. Consider increasing the abstraction of the interface to
			make low impact changes easier to accomplish in the future.</p>

			<p>Take the following example:<br/>
				<code>
					private void appendToList(ArrayList<String> list) {<br/>
					&nbsp;&nbsp;&nbsp;&nbsp;if (list.size() < 100) {<br/>
					&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;list.add("Foo");<br/>
					&nbsp;&nbsp;&nbsp;&nbsp;}<br/>
					}<br/>
				</code>

				The parameter list is currently defined as an <code>ArrayList</code>, which is a concrete implementation of the <code>List</code> interface.  
				Specifying <code>ArrayList</code> is unnecessary here, because we aren't using any <code>ArrayList</code>-specific methods (like <code>ensureCapacity()</code> or <code>trimToSize()</code>).
				Instead of using the concrete definition, it is better to do something like:<br/>
				<code>
					private void appendToList(List<String> list) {<br/>
					...<br/>
				</code>
				If the design ever changes, e.g. a <code>LinkedList</code> is used instead, this code won't have to change.

    		<![CDATA[
    		<p>This method fetches a resource from a URL, and uses the File api to manipulate it. If this resource is a 
    		classpath resource, it will work if the resource is a file in a directory. If however the file is inside a jar file
    		this will fail. Use the URL.openStream api instead to access the data of the classpath resource.
