VirtualHost not working in 2.0

[Gazi Alankus]

Hello, 

I'm a noob and I was able to use VirtualHost objects fine in version 1.1. Now I 
started using 2.0 and VirtualHost won't work. 

When I don't add a VirtualHost, here's an idea of how a request is handled:


Daemon Thread [Restlet-1638726193] (Suspended (breakpoint at line 77 in 
HostRoute))     
    HostRoute.beforeHandle(Request, Response) line: 77  
    HostRoute(Filter).ha​ndle(Request, Response) line: 201      
    ServerRouter(Router)​.doHandle(Restlet, Request, Response) line: 495        
    ServerRouter(Router)​.handle(Request, Response) line: 735   
    StatusFilter(Filter)​.doHandle(Request, Response) line: 156 
    StatusFilter.doHandle(Request, Response) line: 154  
    StatusFilter(Filter)​.handle(Request, Response) line: 203   
    LogFilter(Filter).do​Handle(Request, Response) line: 156    
    LogFilter(Filter).ha​ndle(Request, Response) line: 203

    Component.handle(Request, Response) line: 390       
    Server.handle(Request, Response) line: 474  
    HttpServerHelper(Bas​eServerHelper).handl​e(Request, Response) line: 158    
    HttpServerHelper(Bas​eServerHelper).handl​eInbound(Response) line: 167      
    HttpServerHelper(Bas​eHelper<T>).ha​ndleNextInbound() line: 418     
    ServerConnection(Con​nection<T>).re​adMessages() line: 705  
    Controller$2.run() line: 95 
    ThreadPoolExecutor$​Worker.runTask(Runna​ble) line: 886     
    ThreadPoolExecutor$Worker.run() line: 908   
    Thread.run() line: 637      


When I add a VirtualHost, here's how a request is handled:


Daemon Thread [Restlet-1448851814] (Suspended)  
    VirtualHost$1(Templ​ateRoute).score(Requ​est, Response) line: 243   
    RouteList.getBest(Request, Response, float) line: 96        
    VirtualHost(Router).​getNext(Request, Response) line: 634   
    VirtualHost(Router).​handle(Request, Response) line: 733    
    Server.handle(Request, Response) line: 474  
    HttpServerHelper(Bas​eServerHelper).handl​e(Request, Response) line: 158    
    HttpServerHelper(Bas​eServerHelper).handl​eInbound(Response) line: 167      
    HttpServerHelper(Bas​eHelper<T>).ha​ndleNextInbound() line: 418     
    ServerConnection(Con​nection<T>).re​adMessages() line: 705  
    Controller$2.run() line: 95 
    ThreadPoolExecutor$​Worker.runTask(Runna​ble) line: 886     
    ThreadPoolExecutor$Worker.run() line: 908   
    Thread.run() line: 637      

Note that component.handle() is bypassed when you add a VirtualHost. 

I looked at the pattern matcher, and in the latter it was trying to match 
"/path" to "http://host.com/path"; and failing. I believe that was because 
hostRef was empty string. 

In the former, it matches "/path" with "/path" just fine. 

I feel like the VirtualHost needs to be behind a HostRoute. 

Is this a known problem, or am I doing something wrong and adding VirtualHost 
instances to the component should work fine? 

Thanks,
