Karaf and DOSGi throwing Null pointer Exception
Hi,
I have created a karaf child instance using 'admin:create' command and
installed DOSGi Single-Bundle Distribution (1.3.1) from maven as follows:
I installed 2 other OSGi bundles (service bundle & service implementation
bundle) that implement a simple service (printing sometext).
The service is published under http://localhost:9081/prediction
>From the browser, http://localhost:9081/prediction?wsdl displays WSDL
correctly.
So everything looks fine. But when I exit karaf instance (by pressing
Ctrl+D), I got the following exception:
It is not clear to me, why this exception occurs. Any help towards this is
appreciated.
Thanks.

Hi,
I am not aware of the steps to pull the distribution from trunk?
Can I do get the distribution via maven or via specific download page ?
When I reported this issue, I used the distribution from DOSGi release page,
http://cxf.apache.org/dosgi-releases.html
regards.

I just fixed the NPE on trunk (see
https://issues.apache.org/jira/browse/DOSGI-129).
Can you test it and report if the issue is gone for you?

It might be a similar problem.
As Cellar and CXF DOSGi do not share any code I don think it is the same
thing.

Hi,
Sometime back, I raised a question in stackoverflow about a NPE in Karaf
Cellar
http://stackoverflow.com/questions/12894989/karaf-cellar-throwing-exception-with-blueprint-route-deployment
I believe this is also the same problem (as the exception looks similar).

Though the exception is not causing trouble with my karaf usage, it does not

@raw tag: seams like gmail does not likes it
@error: well, without debugging the code I would simply guess it's
related to something not correctly shutting down the bundles (since
some parts of the framework might not know to be a bundle). But
independently; why does the exception border you? Do you encounter any
"real" errors by it?
Kind regards,
