The cxf-rt-transports-http-3.1.1.jar contains several OSGi HTTP interface classes and the classes are exported in the OSGi Export-Package for the bundle.
The bundle should not export classes from the OSGi HTTP spec in Export-Package; it is the responsibility of the OSGi HTTP service to export the specification classes.
The inclusion of the classes also causes problems for us because we have a Java project with a large classpath (including CXF). We embed an OSGi container inside the outer JVM and we run into problems if CXF is in the outer classpath because the classes in cxf-rt-transports-http-3.1.1.jar cause classloading conflicts with the OSGi HTTP service inside the OSGi container.
You should eliminate the interface classes from the JAR to prevent problems like this.
