It's not the `HttpServer` implementation which opens and closes these file descriptors. Instead it's the (application specific) request handlers - in this case it is the test specific `FileServerHandler` which knows which file to open and server and then close when done. It's done here https://github.com/openjdk/jdk/blob/master/test/jdk/com/sun/net/httpserver/FileServerHandler.java#L121. The `HttpServer` will not know of any resources that these application specific handlers would have opened.
