How to save money on long-term support for Java 11?

TL;TR. During my presentation I will clarify the situation with Oracle JDK and OpenJDK 11+ and compare available solutions to get (free) long-term support (LTS) for your (production) Java instances.

Longer version. Java 11 - besides new features - brought also confusion with the the licensing model. Among others, I will answer the following questions: Is Java still free? Will Java 11 get long-term support from Oracle? Will it be available for free? What is a difference between Oracle JDK 11 and OpenJDK 11? Do I need to upgrade my production to newer Java version every 6 months? What cost-free options do I have to use Java 11 with long-term support? Which option should be best for me (AdoptOpenJDK, Red Hat, Azul, Amazon, Liberica JDK, ...)? Or maybe, in the end, it is worth to pay some $$$ to have support from Oracle?

Just as a pre-warn, please be aware that even the new releases of Oracle JDK 8 (yes 8!) starting with 8u211 (April 2019) are available under the new - non-free for commercial usage - license.

  13. History of Java licensing
    90's - proprietary license
    with source code for (part of) class library available in SDK (src.zip)
    several attempts to create free software Java implementations
    2006/2007 - Hotspot VM, compiler and class library released on GPLv2 (with
    linking exception)
    OpenJDK project as reference implementation of Java SE
    IcedTea emerged to replace parts that couldn't be open sourced
    2007+ - other companies joined OpenJDK (Red Hat, IBM, Apple, SAP, Azul, ...)
    2018 - Oracle JDK binaries built from OpenJDK sources
    with no additional extras (e.g. Java Mission Control)

    View Slide

  14. History of Java licensing - issues
    Technology Compatibility Kit (TCK) available for Oracle's licensees
    provided also for GPL implementations "deriving substantially from OpenJDK"
    but not for other FOSS implementations (such as Apache Harmony and Eclipse
    OpenJ9)
    2018 - Oracle JDK no longer free for production usage
    trademark-related issues with Java/Jakarta EE - not in scope of that presentation

  15. Java vs OracleJDK vs OpenJDK vs ...
    Java - "set of computer software and specifications developed at Sun

    Oracle JDK - distribution of Java SE provided by Oracle
    OpenJDK - open source reference implementation of Java SE
    Eclipse OpenJ9 - Java Virtual Machine (JVM) implementation
    alternative to HotSpot JVM
    possible to use as component of OpenJDK

    multiple ways (vendors) to get
    free basic support for LTS versions (updates)
    commercial extended support
    all security fixes and other important changes should be backported to "vanilla"
    (upstream) OpenJDK source tree anyway
    business relationships, used operating system, target hardware architecture and

    choose your friendly matching vendor

    Java and OpenJDK are here to stay
    even "more" open sourced (let's skip TCK part)
    still available at zero-cost (also in binary form)
    multiple ways (vendors) to get
    free basic support for LTS versions (updates)
    commercial extended support
    all security fixes and other important changes should be backported to "vanilla"
    (upstream) OpenJDK source tree anyway
    business relationships, used operating system, target hardware architecture and
    extra services/tweaks/add-ons may be important
    choose your friendly matching vendor
