Finally got around to discussing this with myself today :)
Long story short, the jai-imageio-core fork for bioformats has been
made to remove *all* dependencies to jai-core which was the important
part. Indeed jai-core is a nasty beast and chance is that it may even
be removed in the future [1]. Technically as soon as you start using
jai-core you get this viral license which forbids you to modify the
source code that use medialib.
Since jai-imageio-core (at least portion of it) list itself as BSD,
bioformats went ahead and remove all code that required jai-core to
compile (mostly in
src/share/classes/com/sun/media/jai/imageioimpl/*.java and
src/share/classes/com/sun/media/jai/operator/*.java). Now we are left
with a self contains jai-imageio were only one non-free component
remains: clibwrapper_jiio.jar. This jar is simply a wrapper around the
shared lib libclib_jiio.so (some kind of static lib of png+jasper, as
can be seen:
$ objdump -d ./src/share/jclib4jai/linux/i386/libclib_jiio.so | grep jas_
$ objdump -d ./src/share/jclib4jai/linux/i386/libclib_jiio.so | grep png
)
So technically all components of jai-imageio are BSD-like, except that
there is a license terms that explicitly restrict this license term:
...

...
What I still do not really understand is that after a git clone of
bioformat I can see I am getting the non-free
./jar/clibwrapper_jiio.jar; but I cannot find the shared lib anywhere.
Should use download/install it separately ?
Thanks

Ps: I spend 1h on this legal stuff, while compilation or
libpng+libjasper should not take more than 10min... oh well
