RRD4j service message (v 1.8.3)

Setting up openHAB 1.8.3.

At start-up I get the following message :

[INFO ] [.p.rrd4j.internal.RRD4jService] - Removing invalid defintion component = null heartbeat = 0 min/max = 0.0/0.0 step = 0 0 archives(s) = []  0 items(s) = []

Tested with a clean install of 1.8.3 with demo setup and got the same message.

Does anyone knows where this comes from, and if I should worry about?

I have seen this since I installed the rrd4j service a few months ago. I looked into it briefly but couldn’t see a cause, so I have just ignored it.

Looks like (although marked as info) a bug, should be fixed with 1.9.
