Hi All Thanks for the votes on the previous release attempt over the holiday period. It looks like I made a mistake with the 7.0.7 release with the wrong artifacts being deployed, and the Activation/JAXB upgrades in 7.1.2 and 8.0.1 meant the activation implementation was dropped (it was part of activation.jar previously). If you were depending on this in your application, you would have seen a breakage.
I've resolved these and will roll further releases later today. Thanks Jon
