NPE in org.jboss.system.ServiceController.start
I checked out the latest CVS yesterday around 7pm GMT and I got an NPE trying to start my own XMLLoginConfig using a modified version of the StackableSecurityConfig described in the JBoss docs:

Apparently the ctx.proxy is null in the ServiceController. This worked with JBoss 3.2.4RC1. Also, here's the code from the StackableSecurityConfig that creates and starts the XMLLoginConfig:
protected void startService() throws Exception
{
// Look for the authConf as resource
ClassLoader loader = Thread.currentThread().getContextClassLoader();
URL loginConfig = loader.getResource(authConf);
if( loginConfig != null )
{
log.info("Using mainSecurityConfigName: '"+mainSecurityConfig+"'");
log.info("Using loginConfigName: '"+loginConfigName+"'");
log.info("Using JAAS AuthConfig: "+loginConfig.toExternalForm());
config = new XMLLoginConfig();
config.setConfigURL(loginConfig);
MBeanServer server = super.getServer();
ObjectName name = super.getServiceName();
name = new ObjectName(loginConfigName);
server.registerMBean(config, name);
config.start(); <------------------- Line 102
Object[] args = {name.toString()};
String[] sig = {String.class.getName()};
server.invoke(mainSecurityConfig, "pushLoginConfig", args, sig);
}
else
{
log.warn("No AuthConfig resource found");
}
}Thanks.
