It appears there's some progress anyway. It's a JAXB-specific issue now. You
can probably add @XmlSeeAlso(MathHelper.class) to MathHelperImpl.class or
tell JAXB to ignore MathHelper alltogether (not sure how...). Now, another
thing to check is : do you allow for all services be handled by DOSGi on the
server side ? If yes then may be DOSGi does indeed tries to create a proxy
on MathHelper...You may need to limit the support for PathObject interface
only...
