5.1.0.20 (Sept 5, 2015)

<p>
	Juno 5.1.0.20 is a moderate update.
	The biggest improvement is the ability to associate external INI config files with REST servlets using the <dc>ConfigFile</dc> functionality.
</p>

<h5 class='topic w800'>Core</h5>
<ul class='spaced-list'>
	<li>Significant API changes to <c>org.apache.juneau.config</c> API.
		<ul>
			<li><dc>ConfigFile</dc> is now thread safe and can be shared across multiple threads.
			<li>New <dc>ConfigMgr</dc> class for managing configuration files.
			<li>Serializers and parsers can be associated with config files for storing and retrieving POJOs.  
				Default support provided for JSON.
		</ul>
	</li>
	<li>New {@link oaj.html.SimpleHtmlWriter} class.  
		Can be used for simple HTML DOM construction.
	<li>New {@link oaj.utils.ProcBuilder} class for calling external processes.
	<li>New <dc>ObjectMap.remove(Class,String,Object)</dc> method.
	<li><js>"class='link'"</js> added to links generated by {@link oaj.html.HtmlDocSerializer}.
	<li>New <dc>EncoderGroup#append(EncoderGroup)</dc> method.
	<li>New <c>HtmlDocSerializerContext.HTMLDOC_addLinks</c> configuration property.
	<li>Modified the <c>Parser.createContext(ObjectMap,Method,Object)</c> method.  
		Outer context objects can be passed in to create instances of non-static inner classes.
	<li>Fixed bug in {@link oaj.html.HtmlStrippedDocSerializer} where exception was thrown when trying to serialize primitive arrays.
	<li>{@link oaj.json.JsonParser} now handles parsing JSON boolean/numeric values as strings to bean properties of type boolean or number. 
	<li>{@link oaj.urlencoding.UrlEncodingSerializer} and {@link oaj.urlencoding.UrlEncodingParser} now 
		represent arrays and collections as key-value pairs where the keys are numbers (e.g. <js>"?0=foo&amp;1=bar"</js>).
	<li>Various internal improvements to {@link oaj.utils.IOPipe}.
	<li>New <dc>ReflectionUtils.getResource(Class,String)</dc> method.
	<li>{@link oaj.internal.StringUtils#parseNumber(String,Class)} now returns zero for empty strings. 
		This affects the way most parsers handle blank values.
</ul>

<h5 class='topic w800'>Server</h5>
<ul class='spaced-list'>
	<li>You can now parse into non-static inner classes of a servlet for parameters/attributes/content.
		Useful if you like to define your marshaller beans inside your servlet.
	<li>Changes to {@link oajr.RestServlet}:
		<ul>
			<li>New methods for accessing external INI config files:<br>  
				<dc>RestServlet.getConfig()</dc><br>
				<dc>RestServlet.createConfigFile()</dc>
			<li>New <js>"$C{...}"</js> variable that resolve to INI config file values.
			<li>New <js>"$UE{...}"</js> variable that  URL-encodes the value inside the variable.
			<li>New convenience methods for retrieving classpath resource files:<br>  
				<dc>RestServlet.getResource(String)</dc><br>
				<dc>RestServlet.getResourceAsString(String)</dc><br>
				<dc>RestServlet.getResource(Class,String,String)</dc>.
					Useful if you want to load predefined POJOs from JSON files in your classpath.
			<li>New <dc>RestServlet.handleNotFound(int,RestRequest,RestResponse)</dc> method for customized handling
				of when a resource or method was not found.  
		</ul>
	<li>{@link oajr.BasicRestServlet}  now automatically processes <js>"/favicon.ico"</js> requests by 
		overriding the new <dc>RestServlet.handleNotFound(int,RestRequest,RestResponse)</dc> method.
	<li>New {@link oajr.RestRequest} methods: 
		<ul>
			<li><dc>RestRequest.resolveVars(String)</dc>
			<li><c>RestRequest.getVarResource(String)</c>
			<li><dc>RestRequest.getConfig()</dc>
		</ul>
	<li>New {@link oajr.RestResponse} methods: 
		<ul>
			<li>{@link oajr.RestResponse#getDirectWriter(String)}.
			<li>{@link oajr.RestResponse#getNegotiatedWriter()}.  
				<c>getWriter()</c> now returns an unnegotiated writer.  
				<c>getUnbufferedWriter()</c> has been removed.
		</ul>
	<li>New {@link oajr.annotation.RestMethod#encoders() @RestMethod(encoders)} and 
		<dc>RestMethod.inheritEncoders()</dc> annotations.  
		Allows encoders to be fine-tuned at the method level.
	<li>New <dc>@RestResource(config)</dc> annotation for associating external <dc>ConfigFile</dc> config files with servlets.
	<li><dc>ResourceLink</dc>.
	<li>New <c>org.apache.juneau.rest.matchers</c> package for commonly-used {@link oajr.RestMatcher RestMatchers}:
		<ul>
			<li>{@link oajr.matchers#MultipartFormDataMatcher}
			<li>{@link oajr.matchers#UrlEncodedFormMatcher}
		</ul>
</ul>
		
<h5 class='topic w800'>Microservice</h5>
<ul class='spaced-list'>
	<li>New juneau-microservice.jar file that encapsulates all 3 juneau jars with code necessary for creating fast and efficent jetty-powered REST microservices.<br>
		Contains the following:
		<ul>
			<li>Jetty 8.0
			<li>Apache HttpClient 4.3.5
			<li>Apache Commons FileUpload 1.3.1
		</ul>
	<li>Microservice now supports Java 6 (previously required Java 7)
