Could we, along with installing Java classes as directories instead of
.jar archive files [0] at a more specific prefix, define a search path
specification that'd set CLASSPATH?  Currently I don't see anything
setting CLASSPATH outside of the build systems, so even if we propagate
Java things, I don't see how it'd find them in a profile.

[0]  Not exactly sure how that's done yet, but it's mentioned here:
