Daniel Godfrey commented on JBEHAVE-368:
----------------------------------------
Yup, java.util.ServiceLoader though, not ServiceLocator. It's being used to
change the guice bindings, but only because of some tangled dependencies
between jars that I've seen no need to fix. It has the benefit of allowing you
to change the modules at runtime, by just changing the classpath.
I'll have a look at the trader guice example, I have a patched local clone of
the repo with the classloader caching fix I mentioned above, but not sure how
I'll manage to work it in the example.

> Key: JBEHAVE-368
> URL: http://jira.codehaus.org/browse/JBEHAVE-368
> Project: JBehave
> Issue Type: Bug
> Components: Maven Plugin
> Affects Versions: 3.0.2
> Environment: Maven 2.2.1 and JDK 1.6
> Reporter: Daniel Godfrey
>
> I'm getting the following stacktrace when using the ServiceLoader
> infrastructure in my JBehave steps while running under the maven plugin. I
> think this is caused by using different class loaders to find the stories and
> then to execute them. It starts working if I patch createClassLoader in
> AbstractEmbedderMojo to cache the created classloader and to reuse that every
> time.
