New Oracle JVM update released, July 16 2019

Note: This blog post is from 2019. Some content may be outdated--though not necessarily. Same with links and subsequent comments from myself or others. Corrections are welcome, in the comments. And I may revise the content as necessary.
Just a heads-up for folks using CF, Lucee, and other Java-based apps and app servers: Oracle has released today a new JVM update, for Java 8 and 11. It's update 221 for Java 8 (1.8.0_221), and update 4 for Java 11 (11.0.4).

For some, that's all they need to know. For most, they will probably want to read on.

I've discussed the matter of JVM updates relative to CF--and several important things to consider--in another post I did for the last update (in April), on the Adobe CF portal: https://coldfusion.adobe.com/2019/04/updates-available-java-8-11-apr-16-2019/. In that, I cover topics such as:

  • Which Java can I use with the version of CF I have installed?
  • Am I really able to use Java 11 (and Java 8 updates after 202) in production?
  • Where can I download the Java updates?
  • How do I update the Java that CF is running?
  • What if I have problems updating the Java that CF uses?
  • What if I have problems applying the CF update (so that I can run Java 11)?

All my answers there are as relevant now as they were then. (That said, whereas that update offered two variants for Java 8, as 211 and 212, this update has only the one, 221.)

Finally, note that as of this writing (5p Central on the 19th), the JVM installers and files are NOT NOW available on the Adobe CF downloads page, section on JVM files. If past experience is a guide, it may not appear for some days. (See my comments in the aforementioned blog post about whether it should "matter" for you, if you could only get the installer from Oracle and not Adobe for some period of days.)

And as I explain in the post, I have other past blog posts that can help if you will be trying the JVM update yourself, or I can help through my troubleshooting consulting.

I amusing ColdFusion 9.0.1 with jdk 1.7.0_75 version. I have to use TLS 1.2 in my systems.

I have tried:

have tried:
-   Added -Dhttps.protocols=TLSv1.2 line to JRun4 > bin > jmv.config file.
-   Installed jdk1.8.0_172 - jdk1.8.0_221 versions and changed JRun4 > bin > jmv.config > java.home path. After that when i want to open web page, opens empty page. It is empty between body tags. Can you help me?

First, it's worth nothing that CF9 was never updated to run Java 8. Still, many have run the two, to solve such problems and it worked (some have had problems, but they could have other explanations, since changing the JVM CF uses is indeed touchy business).

Indeed, as for the blank pages, it could be that something has gone amiss in your attempt to update the jvm and its args--assuming that is indeed all you did. I have a post on several common problems doing that, and how to solve them:


Third, yes it's likely that the change needed to solve your tls problem was indeed the need to update the jvm. I discuss this more here:


Or, if you just want the problem solved, I can help remotely and often quickly via my consulting. See https://www.carehart...
I just tweaked my previous comment, to add the first point now shown there. I should have mentioned it, at the outset, given that you are on CF9.
