----------------------------------------
Hi all,
I just set up a launch configuration for our "productive" bundle.
Whitout the Activator fix from Rajini I get the same exception as in the "test"
bundle. (see above)
Then I added the to the activator and now I get the following exception:
java.lang.IllegalArgumentException: java.lang.reflect.InvocationTargetException

> OSGi bundle design leads to class loading issues
> ------------------------------------------------
>
> Key: TUSCANY-2343
> URL: https://issues.apache.org/jira/browse/TUSCANY-2343
> Project: Tuscany
> Issue Type: Bug
> Reporter: Georg Schmidt
> Attachments: Libary Versions.xls, test_bundles.zip
>
>
> Currently the design of the OSGi bundles leads to class loading exceptions.
> There seem to be several reasons for this behavior:
> * reexporting of all libraries without version numbers
> * imports without version numbers
> Please use distinct bundles for 3rd party libraries. That would lead to
> easier reusage of your bundles in a larger OSGi project.
> The current status leads to undefined system behaviour due to the OSGi class
> loading concept.
> Please tell if you see a way, how we could support you by achieving this
> goal. (If a solution is interesting for you) We are willing to contribute
> because its a critical project issue for us.
> The problems occur with the current snapshot release. Sorry, I do not know
> which version to take.
