Tested with Honeycomb at https://nexus.fd.io/content/repositories/fd.io.snapshot/io/fd/honeycomb/v3po/v3po-karaf/1.0.0-SNAPSHOT/v3po-karaf-1.0.0-20160607.235156-271.tar.gz and VPP from commit 2f0a7a880cece8d3f464be0e481089c6db562fdc. The VPP installs and runs correctly but the Honeycomb fails to boot. Peek at the logs (see attachment) revealed an ugly NullPointerException (whose message suggests that yang file for data object "org.opendaylight.yang.gen.v1.urn.opendaylight.params.xml.ns.yang.v3po.rev150105.VppState" is not correctly installed in the image; searching for a yang file containing this namespace failed, suggesting that most likely this namespace is corrupt) followed by a small bunch of normal log messages and finally ending with a neverending stream of "Lock failed" errors being emitted in one-second intervals.
