Java 11 (LTS) changes the timeline for what $free and free (as in use) Java that the industry is used to. There are $free and free (as in use) ways you can get OpenJDK/Java from Oracle and also production ready OpenJDK builds by other OpenJDK/Java providers such as AdoptOpenjDK, Amazon, Azul, BellSoft, IBM, Red Hat and others. Java 8 has gone through the "end of public updates" process which adds another dimension to what is $free and free.  Come to this panel to ask the gnarly questions about costs, freedom of use, who governs Java/OpenJDK and what providers you can bet your Java infrastructure on for the next 5, 10, 15 years!
