 If you're [pinned](configure-language-java.md#choosing-a-java-runtime-version) to an older minor version of Java, your app might be using the deprecated [Azul Zulu for Azure](https://devblogs.microsoft.com/java/end-of-updates-support-and-availability-of-zulu-for-azure/) binaries provided through [Azul Systems](https://www.azul.com/). You can keep using these binaries for your app, but any security patches or improvements are available only in new versions of the OpenJDK, so we recommend that you periodically update your Web Apps to a later version of Java.
