If you declare an endpoint like
<cxf:rsServer id="testEndpoint" address="address" serviceClass="org.apache.camel.component.cxf.jaxrs.testbean.CustomerService" />
the address is not resolve with the properties.
It would be useful, as it is possible for CxfEndpoint.
You can find with this issue, a small patch with a unit test to reproduce this use case, and a (naive but working) patch that fix the issue for us.
