(This post was written originally in May 2018, 2 months before the release of CF2018 and a few months before the release of Java 11. I have updated it some to reflect changes in that.)
Wondering about CF support for Java 9, 10, 11, or later here in 2018 (with respect to CF 2018, CF 2016, CF 11, or earlier)? Did you know that Java 9 and Java 10 each have only 6-month lives? Seriously. And did you know that Java 9 is already no longer updated, while Java 8 still is (into next year), and that Java 11 is due to come out in September 2018? It can be quite confusing if you've not been paying attention to Oracle's new release model.
What does all this mean for Adobe and CF, and CF users? What versions of CF do, do not, and/or may support these various recent Java versions? The good news is that CF 2018 will come out running (and the second public beta does come running) on Java 10 (no word yet on Java 11). But what about other recent CF versions?
Read on for more.
Update: CF2018 did come out as expected in July 2018, and at first it came out supporting Java 10. Then after Java 11 came out in late 2018, Adobe updated both CF2018 and CF2016 in early 2019 to support Java 11 (or you can continue to use Java 8 while it's supported by Oracle). Adobe also announced in Jan 2019 that they had reached an agreement with Oracle licensing Java 11 and updates to 8 for commercial use with CF. You may want to read my post on the CF portal discussing further when the April 2019 updates for Java 8 and 11 were released by Oracle.
I leave what I wrote below for posterity/historical perspective.
