Executive Summary

• Oracle is making the industry leading Oracle JDK available for free, including all quarterly security updates.  This includes commercial and production use.
• The new license is the "Oracle No-Fee Terms and Conditions" (NFTC) license.  This license for the Oracle JDK permits free use for all users, even commercial and production use.  Redistribution is permitted as long as it is not for a fee.
• Developers and organizations can now easily download, use, share and redistribute the Oracle JDK without needing a click-through.
• Oracle will provide these free releases and updates starting with Oracle JDK 17 and continue for one full year after the next LTS release.  Prior versions are not affected by this change.
• Oracle will continue to provide Oracle OpenJDK releases under the GPL on the same releases and schedule as it has since Java 9.

感觉对一般用户来说，最大的改变就是：

1. JDK 17 可以商用免费。

2. 可以直接通过Oracle官方网站下载。不用像以前那样，还需要注册账户、登录后才能下载。这里是下载链接：https://www.oracle.com/java/technologies/downloads/#jdk17-windows
