Rajini Sivaram commented on TUSCANY-2343:
-----------------------------------------
Daniel,
It still looks like a problem with TCCL, though I dont know why. I think it is
too early to be related to the JAXB issue.
Can you add a try-catch block in ScaDomainActivator.initDomainByContribution
around the code which creates and starts the SCA domain, and include this
snippet of code twice - just before calling EmbeddedSCADomain.start after you
have set TCCL, and in the catch block.
try {
System.out.println("TCCL : " +
Thread.currentThread().getContextClassLoader().getClass());
javax.xml.stream.XMLInputFactory.newInstance();
} catch (Throwable e) {
e.printStackTrace();
}
I would expect to see the print "TCCL : class
org.apache.tuscany.sca.osgi.runtime.OSGiBundleActivator$BundleClassLoader" and
no exception thrown from the call in both cases if it works.

> 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.
