NoClassDefFoundError CommandProcessor/ not found by pax-exam-probe

[bonomat <ph...@gmail.com>]

Hello

I would like to extend the karaf console commands.
But I have some problems writing integration tests:
I have the same setup like the the CoreTest in the package
org.apache.karaf.shell.itests, [1]
but when I try to get the CommandProcessor via :         
CommandProcessor cp = getOsgiService(CommandProcessor.class);
i get the following error: 
java.lang.NoClassDefFoundError:
org/apache/felix/service/command/CommandProcessor.

I have compared the loaded bundles of my karaf instance with an "clean"
karaf and as far as I can see are all necessary bundles present. The whole
stacktrace is at the end of this post.

It must be some kind of ClassLoader Issue and I don't know if I should ask
here or at Ops4J, so I made a double post also at the ops4j mailing-list.

By default your probe, will dynamically import all packages.
All ? Well ... not all! Packages that are exported with provisional status
will not be imported by default.
You will have to modify your probe, like this:

probe.setHeader(Constants.DYNAMICIMPORT_PACKAGE,
"*,org.apache.felix.service.*;status=provisional");

And sorry for the late response !
