Release Highlights
  • Other Notes: Removal of JavaFX from Oracle JDK 8
    As announced in 2020, support for JavaFX on JDK 8, the last commercially supported version of JavaFX from Oracle, ended in March 2025. JDK 8 update 451 is the first upgrade of JDK/JRE 8 without JavaFX. Oracle continues to develop and release JavaFX as stand-alone modules via the OpenJFX project for the latest versions of Java only. For more details see the Java SE Spring 2024 Roadmap Update. Please contact Oracle Sales if you have any additional needs.
    JDK-8341994 (not public)
  • Other Notes: Distrust TLS Server Certificates Anchored by Camerfirma Root Certificates and Issued After April 15, 2025
    The JDK will stop trusting TLS server certificates issued after April 15, 2025 and anchored by Camerfirma root certificates, in line with similar plans announced by Google, Mozilla, Apple, and Microsoft.
    TLS server certificates issued on or before April 15, 2025 will continue to be trusted until they expire. Certificates issued after that date, and anchored by any of the Certificate Authorities in the table below, will be rejected.
    The restrictions are enforced in the JDK implementation (the SunJSSE Provider) of the Java Secure Socket Extension (JSSE) API. A TLS session will not be negotiated if the server's certificate chain is anchored by any of the Certificate Authorities in the table below and the certificate has been issued after April 15, 2025.

Bug Fixes

This release also contains fixes for security vulnerabilities described in the Oracle Critical Patch Update. For a more complete list of the bug fixes included in this release, see 8u451 Release notes.

Java Expiration Date

Oracle recommends that the JDK is updated with each Critical Patch Update. In order to determine if a release is the latest, the Security Baseline page can be used to determine which is the latest version for each release family.

Critical patch updates, which contain security vulnerability fixes, are announced one year in advance on Critical Patch Updates, Security Alerts and Bulletins. It is not recommended that this JDK (version 8u451) be used after the next critical patch update scheduled for July 15, 2025.

Java Management Service, available to all users, can help you find vulnerable Java versions in your systems. Java SE Subscribers and customers running in Oracle Cloud can use Java Management Service to update Java Runtimes and to do further security reviews like identifying potentially vulnerable third party libraries used by your Java programs. Existing Java Management Service user click here to log in to your dashboard. The Java Management Service Documentation provides a list of features available to everyone and those available only to customers. Learn more about using Java Management Service to monitor and secure your Java Installations.

For systems unable to reach the Oracle Servers, a secondary mechanism expires this JRE (version 8u451) on 2025-08-15. After either condition is met (new release becoming available or expiration date reached), the JRE will provide additional warnings and reminders to users to update to the newer version. For more information, see 23.1.2 JRE Expiration Date in the Java Platform, Standard Edition Deployment Guide.
