[Spacewalk-list] Spacewalk 2.7 taskomatic error on startup

Weird, I just got through the upgrade process and after starting spacewalk services I also saw the taskomatic process start and then stop with this error:

simple/http/ProtocolHandler : Unsupported major.minor version 52.0#012java.lang.UnsupportedClassVersionError:
<-- output omitted -->
<-- Wrapper Stopped

My alternatives command shows that current java is set to 1.7.0 openjdk, though 1.8.0 is installed.

I ran alternatives --config java and set it to 1.8.0 and now taskomatic is working again.

________________________________
Follow up: I seem to have found the issue. An additional version of java was installed on the system in the past. Removing that extra version of java and leaving just the openjdk versions allowed taskomatic to startup cleanly and function.

After upgrading to Spacewalk 2.7, taskomatic is failing to start up. The following error is present when attempting to start the service:

Thoughts on where to go? Other than this, the server upgrade seems to be functional.
