Announcing Java updates of Oct 2021 for 8, 11, and 17: resources and thoughts

Note: This blog post is from 2021. Some content may be outdated--though not necessarily.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.
New JVM updates have been released yesterday (Oct 19, 2021) for the current long-term support (LTS) releases of Oracle Java, 8, 11, and 17. (Note that prior to Java 9, releases of Java were known technically as 1.x, to 8 is referred to in resources below as 1.8.) While the news has been announced by Oracle and shared in the IT press, I know that some of my readers don't necessarily follow those sources closely.

The new updates are 1.8.0_311, (aka 8u311), 11.0.13, and 17.0.1, respectively).

For more on them, including information on the security fixes and bug fixes they each contain, see the Oracle resources I list below, as well as some additional info I offer for if you may be skipping to this from a JVM update from before Apr 2021, as well as info for Adobe ColdFusion users on where to find the updated Java versions, what JVM versions Adobe CF supports, and more.

Finding default/initial CF admin config (neo-*.xml) files, now at cfmlrepo.com

Note: This blog post is from 2021. Some content may be outdated--though not necessarily.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.
Have you ever wished to obtain a copy of one CF's neo-*.xml files (like neo-cron.xml), for the purpose of setting yours back to its defaults? Folks sometimes need to do that to recover from certain problems.

I've seen the problem raised often enough that when I saw someone raising it this weekend, I decided to solve it by creating a new folder in the cfmlrepo.com site, at least for CF2021 and CF2018 (for now), offering there the initial versions of all the neo-*.xml files for those two editions.

For more information, see what I shared (including more background on the issue, where I got the files, where I put the files, and more) in my reply about all this to the CF Community thread where the user raised the need this weekend.

And for the sake of those who may "just want the files" without any need of explanation or warnings:

I welcome thoughts, feedback, or suggestions.

Lots more to the current CF2021, 2018 prerelease updates than folks may realize

Here's some good news for those interested in using the Adobe CF Docker images: it turns out you are NOT required to do the clunky "download/docker load" dance that had been announced in this Adobe blog post on Apr 30, the day before the announced closure date of the previous registry they used, Bintray.

This post is about finding and understanding the new, more standard alternatives.

My upcoming talk, "ColdFusion at 25: not the kid most have stuck in their minds"

Note: This blog post is from 2021. 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.
As you may have heard by now, the free Adobe CF Developer Week 2021 will be held June 22-24. My session will be on June 22 at 4p Central in Track 2. While currently the DevWeek site only offers session titles and speakers (descriptions were added after I posted this: click the + sign to the right of each talk), here is mine, from the "presentations" page here on my site:

ColdFusion at 25: not the kid most have stuck in their minds

As ColdFusion turns 26 next month, many seem stuck remembering it only as the "teen" they knew or even the "child", when instead it's grown up to be a capable "adult", impressive in many ways, and even more so recently. In this session, we'll look back at how CF has indeed evolved into a very capable platform, with quite modern features that seem to surprise many--including people working with it currently. If you struggle "finding CF people" or "getting buy-in", perhaps these observations could help you with both challenges. If nothing else, they're things designed simply to help you get your job done, while keeping up with modern practices.

We'll start with many modern coding techniques--which will be familiar to those using more "modern" languages but that many don't realize CF supports, and may have for years. We'll then look at ways that things such as CF installation/deployment, configuration/administration, monitoring, security, and more have improved over the years. And we'll look not only at CF itself but the community surrounding it, ranging from resources for help and learning to tools and services that others have created, making CF a far more complete ecosystem than most give it credit. Put another way: it's not your father's CF!

I look forward to presenting this topic and hope you'll come check it out.

I'll be speaking on the Online CFMeetup this week, on installing CF2021

Note: This blog post is from 2021. 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.
I thought some readers may want to hear that I'll be speaking on the Online CFMeetup this week, specifically "Installing CF2021: choices, challenges, and solutions".

That may sound like a boring or simplistic topic to some. "Doesn't everyone already know how to install CF?" Trust me, they do not. :-) I help people do it every week, whether CF2021 or earlier versions. There are various tips I can and will share, and of course some about CF2021 in particular. But much will benefit you even if still using an older CF version.

For more on the talk, including a description (and my bio) see the meetup event page, which offers details like the URL for attending, the date and time (Thursday at 12p Eastern), and more.

I have just realized that I've been derelict in announcing here on my blog when I'm giving such talks. I did 3 meetup sessions last year, as well as a couple of AMA ("ask me anything") sessions with Dan Wilson, who has been helping me in running the group the past year, with my sincere thanks! :-)

Announcing Java updates of Apr 2021 for 8 and 11: resources and thoughts

Note: This blog post is from 2021. 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.
For those using the Long-term Support (LTS) versions of Oracle Java, 8 and 11, please note `there were new updates released last week (Apr 20), specifically Java 11.0.11 and 8.0_291. For some, that's all they need to hear. They will take that ball and run with it.

For most, you should read on, especially about an important change regarding TLS support (and calling out to servers not yet running TLS 1.2 or above). I cover that and other important topics:

  • What's in the JVM update, do you need to update to it?
  • A key change in this Java update: calls out to TLS 1.1 or 1.0 no longer allowed, by default
  • Re-enabling support for calling out to old TLS versions
  • Groundhog day: you'll need do make this java.security file change on any later JVM updates
  • Should you update to the new JVM version?
  • The importance of testing such updates/changes
  • More questions you may surely have, and finding answers to them
  • Obtaining the updated Java installers

Confirming ColdFusion's Java version, via admin, vars, or code

Note: This blog post is from 2021. 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.
Have you ever wished you could confirm with 100% certainty what Java version is in use by the CF instance you are running? Or where the JVM's location is (in case you are told to modify files related to it)?

Some good news is that ColdFusion offers simple ways/variables that can show you each of these, via the admin or via CFML code. In this post, I discuss both approaches, including a simple single variable which works in CF2018 and above, a variation for those on CF2016 and earlier, as well as variations for Lucee.

Version numbers of libraries underlying ColdFusion 2021

Note: This blog post is from 2021. 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.
Are you wondering what updates have been made (in terms of version numbers) to the libraries underlying CF2021? For instance, what's the version of ehcache? What about Java, Tomcat, Hibernate, Quartz, jQuery, and so on?

In this post, I offer a rundown of what seem the most significant libraries and their versions, as deployed in the first release of ColdFusion (2021 Release).

[Update: I have started updating this post to identify the versions as of update 4, released in May 2022. Rather than wait until I have found ALL the new values, I will just update the list below, clarifying when I have noted the updated value.]

This is something I have been doing in my "hidden gems" talks for the past several releases. I also explain here how I find these version numbers, which isn't always obvious, in case that may help anyone (and also because some libraries may change with future updates to CF2021). I also offer some commentary on why this matter of library versions is important to some, as well as some counterpoints to the demands some have that every library should always be the absolute latest version (and why that's just not practicable).

If you just want the version numbers without the "waffle", look for the bulleted list of them below. :-)

Hotfix released for CF2021 date-mask compatibility issue

Note: This blog post is from 2020. 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.
Good news to share: if you're concerned about being impacted by a pressing compatibility issue in ColdFusion 2021 (regarding using "D" in a dateformat mask), Adobe released a fix for the problem last week. There are 3 simple steps to implementing that fix, one of which is a JVM arg change to that YOU MUST MAKE--even with the "fix" in place--if you want to revert the behavior.

Or you can change your CFML code to get around the problem, as I also discuss below.

[Update: As of Mar 2021, Adobe now offers this "hotfix" as of CF2021 Update 1. You still need to add the JVM arg discussed, if you want to do that:

-Dcoldfusion.datemask.useDasdayofmonth=true

Again, while no longer need to obtain and implement the hotfix jar file itself, the update does NOT change the DEFAULT behavior, which is why that JVM arg is still necessary. The rest of the information below applies.]

Read on for additional details.
