Were you aware that Open Liberty is available under the Eclipse Public

Very cool. I'll give it a test drive. There's work underway on a spring
boot starter
https://openliberty.io/blog/2017/11/29/liberty-spring-boot.html.
Looks like Open Liberty has only been working on z/OS since June
https://github.com/OpenLiberty/open-liberty/issues/425.
Open Liberty was introduced about a year ago now. Yes, Open Liberty is
tested and compatible with z/OS (and with Linux on Z and LinuxONE). The EPL
is an OSI and FSF recognized license. If you have a commercial product and
would like to use Open Liberty as its runtime, that's perfectly fine and no
charge.
WebSphere Liberty and CICS Liberty exploit certain z/OS features that Open
Liberty does not. Thus you have some choices depending on what you'd like
to achieve. As examples, you could (not necessarily mutually exclusive):
1. Distribute and fully support your commercial product with Open Liberty
for those customers that don't want/need the deeper z/OS integration in
IBM's commercial Liberty products, but also support customers who prefer to
deploy your product on WebSphere Liberty, CICS Liberty, or WebSphere
Application Server.
2. Distribute an unsupported trial, demonstration, or basic variant of your
commercial product with Open Liberty, and then license/support customers
who run your full commercial product on WebSphere Liberty, CICS Liberty, or
WebSphere Application Server that they separately obtain from IBM, with IBM
support.

3. Contact IBM to obtain a distribution license for WebSphere Liberty for
your software product, with IBM typically providing you with "Level 3"
support.
4. Distribute your open source software with open source Open Liberty to
everybody, including to z/OS users.
5. Distribute your software product on its own, but provide instructions
and support for running it using Open Liberty, WebSphere Liberty, CICS
Liberty, and WebSphere Application Server. ("Don't have Liberty Profile or
WebSphere Application Server yet? No problem. Visit
https://www.openliberty.io and....")
IBM don't give away freebies on z/OS.
IBM keeps adding lots of no additional charge features to z/OS. How about
the IBM Toolkit for Swift on z/OS as one recent example? The Community
Edition is available at no additional charge and, yes, licensed for
production use:
https://developer.ibm.com/mainframe/products/ibm-toolkit-swift-z-os/
In this particular case, if you'd like optional IBM support services,
there's a separate charge.
Here's another example that I didn't even know about until 30 seconds ago
(as I write this): the free (for 90 days) IBM z/OS Software Checker to
provide you with a simple report of your z/OS software inventory. It's a no
charge subset of IBM Tivoli Asset Discovery for z/OS (circa 2016). Here's
where you can download it:
https://ibm.biz/BdHBSS
If you want to run a report once or a few times within 90 days, and then
never use it again -- because you're doing some sort of upgrade and want to
run a report for an auditor? -- fine, you're allowed, no problem.
To pick a few more examples, various fonts used to be separately chargeable
for z/OS, but now they're included in the base and sometimes useful even if
you aren't printing to paper. The IBM Knowledge Center for z/OS is part of
the base z/OS operating system, and IBM Doc Buddy is free of charge (
https://ibmdocbuddy.mybluemix.net), whereas their ancestors in the
BookManager family were chargeable. The z/OS Client Web Enablement Toolkit
is part of the base operating system.
