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. --Matthew Wilkinson From: [email protected] [mailto:[email protected]] On Behalf Of Miller, Jeffrey L Sent: Wednesday, September 27, 2017 12:30 To: [email protected] Subject: Re: [Spacewalk-list] Spacewalk 2.7 taskomatic error on startup [This is an external email.

Removing that extra version of java and leaving just the openjdk versions allowed taskomatic to startup cleanly and function.
