Yep, it's environmental and installed by the user. If we had a JNLP,
then the JDK might do an automatic upgrade or something; but I think
you get a click through license.

The answer I've always seen on this is that it has to be apparent to
the user that they are installing them, and that they see the license;
rather than magic that happens in the background.
