The following error is encountered when attempting to use KubePing with library version 0.9.1 and jgroups 3.x (tested on 3.6.12.Final):

The apparent cause is that the org.jgroups.Message#setSrc method has different signature in JGroups 4.0 which 0.9 is compiled against.

The allowed jgroups versions are specified as [3.6.10.Final,4.0] in the pom, so i would assume 3.x still has to be supported

Yes, of course. That's a regression. I'll fix and release 0.9.2. Thanks for spotting this!
