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?

In our spot tests, we have not seen any performance difference or idiosyncratic behavior. Today, their differences seem more about licensing and support, and less about technology.

Earlier quoted context omitted.

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?

Correct. But the chances that you're using any of those features is extremely low.

Most of the differences are commercial features you're not allowed to use without a commercial support contract with Oracle. The only other differences are so small you probably wouldn't notice.

I’m honestly surprised they didn’t go with “Simple Java Service”. /s

Opening this up to the world should be not so subtle hint to answer your question with real world experience.

Probably because they don’t own the trademark on Java.

I'll take names over alphabet soup. My EBS EC2 machines are not playing nicely with ELB (but my EFS ones are), I think it might be to do with EMR, or maybe EKS.

Well, it's corrected coffee, which matches their intention and general java/beans/jar theme. I kinda like it.
