Java 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 8u91) will expire with the release of the next critical patch update scheduled for July 19, 2016.

For systems unable to reach the Oracle Servers, a secondary mechanism expires this JRE (version 8u91) on August 19, 2016. After either condition is met (new release becoming available or expiration date reached), Java will provide additional warnings and reminders to users to update to the newer version.
