I have been seeing these random logs in syslog on our production system.
There is no XFS setup. Fstab only shows local partitions, only EXT3 . There is nothing in crontabs either.

The only file system related package I have installed is 'nfs-kernel-server' Kernel version is 3.2.0-31-generic .

Why would this randomly show up? This also spawns multiple "jfsCommit" processes.

These aren't random, they are part of os-prober determining partitions and then installed OSes before the system configures/installs a new kernel. If you have security updates enabled this can happen without you doing anything.
