Presentation plan history of Java licensing Java vs Oracle JDK vs OpenJDK vs ... OpenJDK development (licensing) changes for Java 11+ long-termin support options Marcin Zajączkowski @SolidSoftBlog https://blog.solidsoft.info/

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) Marcin Zajączkowski @SolidSoftBlog https://blog.solidsoft.info/

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 :) Marcin Zajączkowski @SolidSoftBlog https://blog.solidsoft.info/

Java vs OracleJDK vs OpenJDK vs ... Java - "set of computer software and specifications developed at Sun Microsystems" - trademarked by Oracle Java Platform, Standard Edition (Java SE) - base part of Java 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 developed by IBM, donated to Eclipse Foundation in 2017 Marcin Zajączkowski @SolidSoftBlog https://blog.solidsoft.info/

Importance of using supported version Marcin Zajączkowski @SolidSoftBlog https://blog.solidsoft.info/

Importance of using supported version public updates (aka supported version) - new versions are released security fixes mostly for Java Web Start, but JDK server side can be also affected bug fixes and new features e.g. better support for running inside container (cgroups constraints) Marcin Zajączkowski @SolidSoftBlog https://blog.solidsoft.info/

Importance of using supported version public updates (aka supported version) - new versions are released security fixes mostly for Java Web Start, but JDK server side can be also affected bug fixes and new features e.g. better support for running inside container (cgroups constraints) (extended) support help from vendor engineers in solving your own issues at least hope to get it... faster fixing reported bugs (should have higher priority) extra paid Marcin Zajączkowski @SolidSoftBlog https://blog.solidsoft.info/
