[Jetty-support] NPE stopping HttpServer.java
|
From: Alexey Y. <Al...@fr...> - 2004-09-27 08:04:17

I am running Jetty 4.2.21 inside JBoss 3.2.5. In production environment, =
when I stop JBoss, I am getting an NPE in HttpServer.java. In my dev. =
configuration, this does not happen. At the bottom of this message you =
can find my listener configuration. Apparently, somehow =
HttpServer.destroy() is called before HttpServer.stop().
