Hi Nam,

read the docs :-)

guix environment PACKAGE

is setting up an environment FOR developing PACKAGE, i.e. all its
dependencies/compilers are added to the environment.

If you want to have a package directly IN the environment, use the
--ad-hoc switch:

guix environment --ad-hoc PACKAGE

You can even combine both, for example to add more tools:

guix environment --pure guix --ad-hoc git

That would create a pure environment where the git command is
available and all tools to develop guix. The guix command is not in
here!

In your case, IcedTea 2 is used to develop IcedTea 3, that's the reason
why you found that in your environment.

Finally, you can add a "-- command" to the environment to execute a
command, so this should tell you the right version and afterwards
automatically exit the environment(-C == --container, to be absolutely
sure):

$ guix environment -C --ad-hoc icedtea <at> 3.7:jdk -- javac -version
javac 1.8.0_161


I'm closing that bug,

Björn
