Earlier quoted context omitted.

Lack of long-time support commitment. A lot of java users want to hear someone say "we'll push updates for any and all CVEs for the next forty-two years, and that's a promise". They may not actually install those updates, but they want to hear someone say that they will exist.

But isn't it exactly what Oracle offers? For the money, of course.

Oracle's offering involves paying Oracle money and getting regular phone calls from the Oracle sales department, which I have heard described in colourful ways.

At which point will they add their proprietary extensions? Am I the only one fearing this? I wouldn't want to depend on a business like Amazon.

Oracle always has proprietary parts in the JDK and that was no problem for people.

> Amazon Corretto is a no-cost, multiplatform, production-ready distribution of the Open Java Development Kit I really, really wish AWS would start using practical/self-explanatory names for their products.

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.

Everybody loves a good TLA!

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?

James Gosling, says that Amazon uses Corretto in production...which is OpenJDK. So most of AWS/Amazon uses that.

Surely Amazon Corretto is just going to fracture the Java ecosystem?

It's already split between Java8 laggards and Java11. Spark for example hasn't been able to upgrade to Java9 due to their use of some Unsafe stuff. Hadoop just upgraded from 7 to 8 last year.

This is about Amazon removing a revenue stream from Oracle. Amazon also announced a few days ago that they were removing Oracle products from AWS. Expect an article by Ben Thompson on stratechery.com in the next week.

To be fair I trust Amazon just about as much as I trust Oracle.

You can get Open JDK from any of the following places on them intarweb tubes, and they don't seem to fracture the ecosystem. Linux is available from many places, it may seem fractured, yet Linux seems to be taking over the world. Even Microsoft now "loves" Linux.

Amazon is moving their own systems off Oracle; I don't see anything in those stories about Amazon ending AWS customers' Oracle deployments.

I don't really "get" software licensing but are they bound to GPL because OpenJDK is GPL? Does anyone make a more permissive JDK?

Yes, but it's really GPLv2 with the classpath exception [1] which makes it similar to the LGPLv2. Amazon's OpenJDK still has to be GPL. However, software using the OpenJDK can be licensed however you want (because of the classpath exception) [2].

The repo is on Github: https://github.com/corretto

Cool thanks for posting that link. Quickly looking through the commits. It looks like it was forked off the official JDK 8 a few months ago. Since then, Amazon has been busy with mostly backporting fixes from later versions of the JDK.

It also seems they have licensed oracle's test suite. So, it is supposedly passing that.

So based on the above, this looks like they are serious about LTS and if you are using java 8, this might be a good build to rely on.
