Apache Aries JAX-RS Whiteboard > = 1.5.0 causes java.lang.ClassCastException
Hello all,
I recently upgraded to JAX-RS Whiteboard 1.6.0 (was using 1.1.0) and I'm
experiencing some class loading issues related to CXF. One of the
components in my application exposes a CXF based web service that is now
failing with the following stack trace:
java.lang.ClassCastException: Cannot cast
org.apache.cxf.service.factory.FactoryBeanListenerManager to
org.apache.cxf.service.factory.FactoryBeanListenerManager
at java.lang.Class.cast(Class.java:3369) ~[?:?]

I think this is related to the change made in 1.5.0 where the JAX-RS
Whiteboard team changed the way CXF is embedded.
I'm using CXF 3.2.5 with Karaf 4.2.6

I can't think of anything like this from the top of my head. Do you have
any shell (like gogo shell) in which you can trace where the packages
are being imported from? Maybe that would shed some light on why this is
happening.

none that I can think of, I am afraid :-(
That's one of the drawbacks of heavy use of lambdas. I have been looking
into ways to improve on this, but with no luck so far. Any ideas are
welcome.
Thx.

Hi Carlos,
I think that is the case but I can't find the cause. To give you a better
idea of the situation, we have a bundle (Bundle A) that launches a CXF
server that will publish a SOAP WS at port 8085. We then have another
bundle (Bundle B) providing a few REST endpoints that will be published by
JAX RS whiteboard using the default Karaf Jetty server (port 8181). If the
JAX RS whiteboard bundle is installed, when Bundle A starts it will fail
with the ClassCastException. Bundle B doesn't use CXF and doesn't need to
be installed for the issue to happen.
As a workaround I reverted back to JAX-RS Whiteboard 1.4.0
Out of topic. The decision to use the Aries DSL to register services
results in cleaner code but makes stack traces longer and almost
unreadable. Debugging is also harder. Do Aries contributors have any
techniques to make it easier ?
Thank you for your time.

Hi there,
is it possible that your application and the whiteboard are importing
FactoryBeanListenerManager from different bundles?. In order to use CXF
directly with the whiteboard you would need to export the packages from
the whiteboard using a fragment and then import them from your bundles.
Carlos.
