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 8u144) will expire with the release of the next critical patch update scheduled for October 17, 2017.
Seems to be hardcoded in the installer.
