> When setting log level to trace, NPE occurs in method invokeInContexts of RootInterceptor class.
> According to the EJB 3 spec, p. 308, method getMethod of class InvocationContext returns null for lifecycle callbacks.
> The invokeInContexts method is invoked in the PostConstruct, resulting in a NPE: 
>             log.trace("intercepted: " + getComponent().getName() + '.' + invocation.getMethod().getName());
> Locally patched this way:
>    private Object invokeInContexts(InvocationContext invocation, EventType eventType) throws Exception
>    {
>       if ( isProcessInterceptors() )
>       {
>          if ( log.isTraceEnabled() ) 
>          {
>         	 //FIXME Fixed problem with the invocationContext in @AfterConstruct getMethod() returns null! (see spec p. 308)
>         	 log.trace("intercepted: " + getComponent().getName() + '.' + ((invocation.getMethod() !=null) ? invocation.getMethod().getName() : "POSTCONSTRUCT"));
>          }
>          return new SeamInvocationContext( invocation, eventType, userInterceptors, getComponent().getInterceptors(type) ).proceed();
>       }
>       else {
>          if ( log.isTraceEnabled() ) 
>          {
>             log.trace("not intercepted: " + getComponent().getName() + '.' + invocation.getMethod().getName());
>          }
>          return invocation.proceed();
>       }
>    }
