      Something to look into....

      tests that use JettySolrRunner frequently fail with stack traces like this...

      java.net.BindException: Address already in use
      	at java.net.PlainSocketImpl.socketBind(Native Method)
      	at java.net.PlainSocketImpl.bind(PlainSocketImpl.java:359)
      	at java.net.ServerSocket.bind(ServerSocket.java:319)
      	at java.net.ServerSocket.<init>(ServerSocket.java:185)
      	at java.net.ServerSocket.<init>(ServerSocket.java:141)
      	at org.mortbay.jetty.bio.SocketConnector.newServerSocket(SocketConnector.java:78)
      	at org.mortbay.jetty.bio.SocketConnector.open(SocketConnector.java:72)
      	at org.mortbay.jetty.AbstractConnector.doStart(AbstractConnector.java:252)
      	at org.mortbay.jetty.bio.SocketConnector.doStart(SocketConnector.java:145)
      	at org.mortbay.component.AbstractLifeCycle.start(AbstractLifeCycle.java:40)
      	at org.mortbay.jetty.Server.doStart(Server.java:221)
      	at org.mortbay.component.AbstractLifeCycle.start(AbstractLifeCycle.java:40)
      	at org.apache.solr.client.solrj.embedded.JettySolrRunner.start(JettySolrRunner.java:89)

      ...because they have a hardcoded port number in them. it occurred to me tonight that java.net.ServerSocket will pick a port for you automaticly if you specify a port of "0", the real port can then be accessed by getLocalPort().

      we should see if passing 0 to Jetty's "Server" class works, and if in doing so we can then add a method to JettySolrRunner to introspect the actual port after starting the server (from the Jetty javadocs this seems possible by calling jettyServer.getConnectors()[0].getLocalPort() ... with some error checking of course).

      then we could change all the relevant tests so that instead of a hardcoded port number, setUp assigns a value to port after the Jetty Server is started.
