I checked that the version 12.4(11)XJ has a bug CSCsk50423 , which is fixed in 12.4(11)XJ6, but I can't find it. The version available is 12.4(11)XJ4.
The XJ track is built upon the T track with additional features for Wireless.
If you aren't using this router as a wireless router, I recommend downloading the T track instead as this bug does not affect that release.
12.4(15)T7 or T8 seems to be a solid release.
it means that your image implements the features that are in 12.4(11)T.
Or you can see your image as a variation of main T technology image 12.4(11)T
so if you are not using very specific features that are only in XJ you could move to an 12.4(XX)Ty
you can use
to compare images
you can compare last of XJ train and a 12.4T image I don't know if spservices is present in 12.4T.
Hope to help
