java.lang.NullPointerException when packaged with exclude-swf-files

[pablojr]

If profile exclude-swf-files is used, resulting .jar file lacks folder static/... (which is Ok for the ones like me providing the SWF files for flashsocket from a separate HTTP server, see #42) but socket.io server throws NPE since there are hardcoded references to such files under static/...
