Rajini Sivaram commented on TUSCANY-2343:
-----------------------------------------
Daniel,
Could you run the test through the debugger with breakpoints on the line "
javax.xml.stream.XMLInputFactory.newInstance(); " in both the cases? When you
get to this line, could you set breakpoints on the methods "getResource" and
"findClass" in OSGiBundleActivator.BundleClassLoader? I would like to make sure
that
1) The same OSGiBundleActivator$BundleClassLoader object is used in both
cases
2) The "bundles" field of this object contains around 200 bundles
3) getResource("META-INF/services/javax.xml.stream.XMLInputFactory") when
called returns a valid URL in both cases
4) findClass("com.ctc.wstx.stax.WstxInputFactory") should get called in both
cases, and should return a class from the bundle (the first return statement).
Sorry, I really dont have a clue what is broken...

> 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.
