PTC's new policy on Java starting January 2019

I'm trying to digest the customer communications with the aim of figuring out how to get around this with the fewest problems.  I deal mostly with Windchill, Pro/Intralink and Creo. So far, I'm thinking that staying with the products released before January 2019, however the Customer Letter seems to indicate that they are removing the JDK downloads....?

"The following products currently ship Java with the PTC product installer as well as ship updates to Java.
Starting January 2019, you will need to obtain and install Java as a prerequisite for installing or re-installing these PTC products. For these products you will need to secure a support contract directly with Oracle for updates to Java, including security patches.
-Arbortext Content Manager
-Pro/INTRALINK
-Creo Parametric, Creo Options Modeler, Creo Layout and Creo Direct
-FlexPLM
-Windchill based products and associated extensions"

I expect more technical info will be forthcoming.  "You will need to obtain and install Java as a prerequisite for installing or re-installing these PTC products" just seems too simple and dismissive. Beyond that, there is an additional vendor and additional expense to deal with now.  Will need to figure this into estimates for new work and upgrades for our customers. And who knows whatever other unpleasant surprises that huge changes bring.  Oh hooray.
