How is Corretto different from OpenJDK?

Corretto is a distribution of Open JDK with patches included by Amazon that are not yet integrated in the corresponding OpenJDK update projects. We focus on patches that improve performance or stability in OpenJDK, chosen based on Amazon’s observations running large services.

What is included in Corretto’s long-term support?

Amazon will provide security updates for Corretto 8 until at least June 2023. Updates are planned to be released quarterly. Corretto 11, corresponding to OpenJDK 11, will be available during the first half of 2019. Amazon will support Corretto 11 with quarterly updates until at least August 2024.
