I'm on jdk-tool:1.1 and Jenkins 2.138.2.  I've configured JDK10 in Global Tools per the attached screenshot.  When running a job that uses it, I get:

Installing JDK jdk-10.0.2-oth-JPR

I believe these URLs should be:

http://download.oracle.com/otn

instead of:

http://download.oracle.com/otn-pub

I've tried using other installer methods such as Extract .zip/.tar.gz and also the Custom Tool plugin instead, but these lack the authentication-handling needed to download JDK from Oracle.
If the "Install from java.sun.com" method is currently broken, how are people using the official JDK with Jenkins?  Doesn't seem to be a public docker image for it.  Is everyone using openjdk instead?  Or maintaining their own jdk docker images?
