Claus, thanks for the reply.
Ok I tried that, however, if in the bootstrap code in main just before
calling run() I place
List<CamelContext> contexts=getCamelContexts();
System.out.println(contexts); // []
CamelContext context=contexts.get(0);
//IndexOutOfBoundsException: Index: 0, Size: 0
context.getManagementStrategy().addEventNotifier(new
MyLoggingSentEventNotifer()); //as in
http://camel.apache.org/eventnotifier-to-log-details-about-all-sent-exchanges.html
run();
It produces
[]
Exception in thread "main" java.lang.IndexOutOfBoundsException: Index: 0,
Size: 0
Is this a bug or am I doing something wrong?
