You won't have to pay for using Oracle JDK 8u181 in prod, and you won't have to pay for using OpenJDK 11 and higher in prod.

You will have to pay for using Oracle JDK 11 and higher in prod, which is built from the exact same codebase as OpenJDK 11 but offers commercial support and long-term support (LTS) releases.

https://adoptopenjdk.net plans to ship LTS releases of OpenJDK for free.

Ok, thanks!

But I'm pretty sure the superior performance of the closed source Oracle JVM will never be open-sourced.

It's the only value Oracle has left, and they know they cannot exploit it, even if this is a nice try.

Of the 2 million Java coders there are atleast 1% that care enough to look at building a 100% open-source VM language.

I hope James Gosling is building exactly that at Amazon.

As of 11, a "closed source Oracle JVM" won't exist anymore, and there won't be any performance difference between Oracle JDK and OpenJDK.

If so my guess is Oracle will be gone within 10 years.
