[Hawkular-dev] errors when embedding c*
We have embedded C* today using the maven 'embeddedc'
profile.
HOWEVER, I can tell you that that still doesn't work quite right
...
some components throw errors at startup and you usually have to
shutdown the h-server, restart it, and usually (not always) things
start working again.
Whether we embed C* in -services or in another distro, either way, we have a problem.
I'm sure all of us have seen this at one time or another :)
It seems if I restart the server, most times (not all) I no longer see these errors. I
have no idea if this is just going to cause problems in alerts, or if there are other
problems we'll see. But I see lots of these kinds of errors:
