Subject Re: [PROPOSAL] Docker feature in Karaf container
Date Mon, 05 Feb 2018 09:18:11 GMT
Hi guys,

quick update about this. I removed the blueprint dependency to use the same
approach as other Karaf modules (BaseActivator). I also started to use the JAXRS
spec instead of CXFRS backend.
I started an local integration branch this morning. I should create a PR
including utests/itests, features and so on tomorrow.

Thanks !
Regards
JB
