Description

See CAMEL-8647

If you run Karaf on Java 7, then javax annotation 1.1 is exposed by default (see etc/jre.properties). And when using Java 8, its javax annotation 1.2.

CXF 3.1.x uses javax annotation 1.2 and then it causes osgi package problems.

karaf@root> features:install camel
karaf@root> features:install camel-cxf
Error executing command: Can't install feature camel-cxf/0.0.0:
Could not start bundle mvn:org.apache.cxf/cxf-rt-rs-extension-providers/3.1.2 in feature(s) cxf-jaxrs-3.1.2: Uses constraint violation. Unable to resolve bundle revision org.apache.cxf.cxf-rt-frontend-jaxrs [118.0] because it is exposed to package 'javax.annotation' from bundle revisions javax.annotation-api [79.0] and org.apache.felix.framework [0] via two dependency chains.

Chain 1:

     |
