Hello i use vertx on Karaf everything is ok but when i want to run an 
vertx http server (just http)

vertx.createHttpServer()
        .requestHandler(router)
        .listen(8080)
        .onSuccess(LOGGER::error)
        .onFailure(LOGGER::error);

i get this error java.lang.NoClassDefFoundError: 
javax/net/ssl/TrustManager (i also get this one in karaf log:  Using the 
default address resolver as the dns resolver could not be loaded)
