There are a bunch of things we do that require a fully working and stable version of JAXB which is not something you really get if you completely depend on the version in the JDK. The version in the JDK will depend completely on what version of the JDK you grab (1.7.0_01 vs 1.7.0_07 for example) with each having different bugs and such. In addition, some of the new features that have been developed recently require the jaxb-impl, not the in-jdk version. In particular, we added the ability to control the namespace prefixes and locations that are output when using the JAXB component. That requires the jaxb-impl as all the package names are different for the in-jdk versions. If you don't use the camel jaxb component/databindings and you can live with the bugs and issues from the in-jdk version, you can likely use the exclusion. However, you may be better off with adding a more recent and stable JAX-WS implementation as a dependency (CXF 2.7.0 for example or even the latest RI: http://repo1.maven.org/maven2/com/sun/xml//ws/jaxws-rt/2.2.7/) which should be set to work correctly with the jaxb-impl dependency.
