Thanks for the diagnose, ‘guix package -r icedtea:out -u icedtea:jdk’
worked nicely!

I was unaware that ‘icedtea:out’ and ‘icedtea:jdk’ were not meant to be
installed in the same profile.  In fact I find it confusing since in
general package outputs are used to add things that are optional (doc,
debug, ...) more than defining alternative.
