Uh, I looked through one of my Java-related packages and found this snippet:

----------
;; Set JAVA_HOME to help maven find the JDK.
(setenv "JAVA_HOME" (string-append (assoc-ref inputs "icedtea")
                                   "/jre"))
----------

So perhaps JAVA_HOME needs to point to <profile-root>/jre.  (Sorry for the
previous suggestion..)

I'm not sure why I added this snippet though, but perhaps it's worth a try.

Kind regards,
Roel Janssen
