OpenJdk 11 vs OpenJdk 13 Adoption

[Ben Evans]

Hi Steven,

As part of my day job (Architect for JVM technologies at New Relic) I
produced this report:
https://blog.newrelic.com/technology/state-of-java/ back in March

It's based on the actual observations of which JVMs our customers are
running in production. We see data from 10s of millions of JVMs every
day.

The pattern is clear - very few companies are choosing to use the
versions of Java that are not long-term support releases (Java 8 and
11 are the only LTS releases currently. Java 13 is not LTS and is
already EOL).

The numbers have moved a bit - we now see 15-20% of users running Java
11 and ~80% running Java 11, but the general pattern remains the same.

The most popular distribution for Java 11 that provides ongoing
updates for free is AdoptOpenJDK - https://adoptopenjdk.net/ - which
is becoming part of the Eclipse Foundation. If you are heavy users of
AWS you may also want to consider Amazon Corretto.

Thanks,

Ben
