Keeping the JDK up to 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 7u343) be used after the next critical patch update scheduled for July 19, 2022.

Java SE Subscription customers managing JRE updates/installs for large number of desktops should consider using Java Advanced Management Console (AMC).

For systems unable to reach the Oracle Servers, a secondary mechanism expires this JRE (version 7u343) on 2022-08-19. 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.

Stricter path checking however prevents the use of special devices such as NUL:



Bug Fixes

This release is based on the previous CPU and does not contain any additional security fixes.
