​You can definitely download JDK via wget.  ​
I have a script that
​
discovers the latest JDK, downloads it,
​uses
java.Slackbuild in /extra to build a package, and installs it.  This is my
wget command to download the latest JAVA once the script has located the
proper URL:

  wget -q --no-check-certificate --no-cookies --header "Cookie:
oraclelicense=accept-securebackup-cookie" "${JAVA_DOWNLOAD_URL}"

This works as long as you find the actual download URL
​ and​
not a URL that redirects to the
​actual ​
download
​ URL​
.
​  I found this by using HttpFox on Firefox to see what was happening when
I clicked through the website and downloaded via a browser.  It's important
to understand that you are still accepting the license agreement by using
wget to download it.

​I suspect Slackbuilds is against this practice for a number of reasons,
especially the possibly too magical discovery of URLs via text parsing of
HTML.  But it's something to consider.  Another idea might be an optional
WGET_OPTIONS="" field in the jdk.info file.  That would tell automated
tools like sbopkg what extra command line options are needed to download
from the URL given in jdk.info.
