    LittleCMS 1.x  didn't provide the support necessary to pass JCK. So 
we talked to
    the LittleCMS maintainer and he added the necessary APIs in 2.0
    JDK 7 has had LittleCMS 2.0 for almost 6 months now and that is 
included without any code
    modifications, so I think it should now be possible to use a system 
library, although
    we didn't do the work to actually enable that, so its built into a 
JDK library which
    has the littlecms code and the glue code. We need to provide the 
ability to separate these.
    When we pushed LCMS 2.0, I asked for a bug to be filed to remember 
to do this work
    but I can't find it in the database. I'll ask for that to be filed 
if it wasn't already.
    NB It didn't seem super-urgent since we pulled in LCMS 2.0 
relatively soon after its release
    we thought shipping distros weren't likely to have the library 
upgrade anyway, but that's
    probably changing.
