I have not used Java in many years now, but I'm curious if anyone has anecdotal experience using OpenJDK in production? Performance vs Oracle Java, bugs/ idiosyncrasies due to internal API differences, etc?

As of JDK 11, there is feature parity between OpenJDK and Oracle JDK, which is the JDK that most people used until now. In JDK 8, the Oracle version had several closed source additional features (such as Java Flight Recorder and the Z garbage collector). Also, implementations of things like graphics rendering used to be different in Oracle JDK 8 and earlier. That's no longer the case. Oracle JDK and OpenJDK should be…

Amazon's OpenJDK is 1.8.0 which is JDK8, so it still 'misses' those Oracle's closed features?

Used OpenJDK in production for years. Never seen any issues or bugs. And with the changes in the OracleJDK license going forward we are essentially forced to use OpenJDK.

Legitimate question: what is keeping stock OpenJDK from being considered "production-ready" as it is?

See this link for context: https://jaxenter.com/end-life-comes-early-jdk-8-140824.html Tl;Dr: with Oracle changing the release versioning of Java, LTS releases are now essentially a paid product. If you run a large business with a lot of Java that is now a significant new burden to deal with.

And also perhaps a rising desire at Amazon to take Oracle down a few notches, as also seen in the recent “uh huh, keep talking Larry” announcements? EG: https://www.theregister.co.uk/2018/11/12/stay_classy_jassy_g...

It's a bit sad that they don't even package it in Amazon Linux's repos. In my eyes that's just building trust on one end and demolishing it on the other.

I'd bet it's a matter of time - once they see it mature and/or requested enough I am sure it will end up there.

We've been using OpenJDK in production since Java 7 without issue. Since Java 8, Oracle JDK has been built from OpenJDK with a couple of proprietary editions (Java Flight Recorder, SNMP support, different font rendering etc.).

In practice, none of the differences had any impact on our uses.

Since Java 11, Oracle JDK and OpenJDK are the same. Oracle JDK is just a build that's commercially supported by Oracle.

There's a ton of FUD around OpenJDK and has been for years. For a long time many Apache projects recommended Oracle JDK solely on the grounds that they hadn't been tested on OpenJDK by the maintainers.
