I tried to update an old Spur image, and somehow Character >> 
#isAlphaNumeric from Collections.spur-ul.628 (which should be loaded by 
update.spur-ul.311) appeared in the image, while loading 
Collections.spur-tfel.623 from update.spur-mt.310.
Assuming that the load order of the packages is untouched, I suspect that 
the method got merged in from the non-spur branch of Collections somehow.
