The condition specification is part of OSGi R8 Core and Compendium releases. The OSGi R8 Core (Framework) implementation is available now with implementations available from Felix and Equinox. The condition factory specification is in the works but is not going to be included with the OSGI R8 specifications ( https://github.com/osgi/osgi/blob/design/168/.design/design-168.md). But the declarative services specification for OSGi R8 has been updated to include how conditions can influence service components. A release candidate of Felix SCR 2.2.0-RC1 will be available shortly that implements the latest OSGi R8 release candidate APIs. The final release of OSGi R8 compendium will hopefully be released by October. All of that means that it is not available in Karaf at this time.
