JRE Expiration Date

The JRE expires whenever a new release with security vulnerability fixes becomes available. Critical patch updates, which contain security vulnerability fixes, are announced one year in advance on Critical Patch Updates, Security Alerts and Third Party Bulletin. This JRE (version 8u77) will expire with the release of the next critical patch update scheduled for April 19, 2016.

For systems unable to reach the Oracle Servers, a secondary mechanism expires this JRE (version 8u77) on May 19, 2016. 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 JRE Expiration Date.


This Security Alert (8u77) is based on the earlier 8u74 PSU release. All users of earlier JDK 8 releases should update to this release. For more information on the difference between Critical Patch Updates and Patch Set Updates please visit Java CPU and PSU Releases Explained.

The demos, samples, and Documentation bundles for 8u77 are not impacted by the Security Alert for CVE-2016-0636, so version 8u73 demos, samples, and Documentation bundles remain the most up to-date version until the April Critical Patch Update release.
