Hi,

I built CounterInterceptor from source codes which were provided in jboss-4.0.0-src/varia/src/main/org/jboss/varia/counter/*.

I deployed the generated counter-plugin.jar, counter-service.xml which is also provided, and modified standardjboss.xml.

The interceptor would work quite normally befere.
It still works fine while running jboss.
But when I stop jboss process, the following error occurs.

Any idea will be greatly appreciated.
