------------------------------------------------------------
I experienced this issue when tried to upgrade from 3.4.10 to 3.5.5.
A workaround (for me) would be to add
_serviceAnnotation="org.springframework.stereotype.Component"_ to my
_jaxrs:server_ definition.
I've prepared example project to demonstrate this issue: [^cxf-bug-test.7z]
You can try to change cxf-version in pom.xml from 3.4.10 to 3.5.10, and you'll
see that it's a regression defect.
In order to solve this defect in CXF source code you only need to change from
??} else if (serviceAnnotationClass != null && !serviceBeansAvailable &&
!providerBeansAvailable && !resourceProvidersAvailable)??
to
??} else if (serviceAnnotationClass != null || !serviceBeansAvailable &&
!providerBeansAvailable && !resourceProvidersAvailable)??
like it was before.
