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 8u192) will expire with the release of the next critical patch update scheduled for January 15, 2019.

For systems unable to reach the Oracle Servers, a secondary mechanism expires this JRE (version 8u192) on February 15, 2019.

New Features


Support for Customization of Default Enabled Cipher Suites via System Properties 

The system property jdk.tls.client.cipherSuites can be used to customize the default enabled cipher suites for the client side of SSL/TLS connections. In a similar way, the system property jdk.tls.server.cipherSuites can be used for customization on the server side.

The system properties contain a comma-separated list of supported cipher suite names that specify the default enabled cipher suites. All other supported cipher suites are disabled for this default setting. Unrecognized or unsupported cipher suite names specified in properties are ignored. Explicit setting of enabled cipher suites will override the system properties.

Please refer to the "Java Cryptography Architecture Standard Algorithm Name Documentation" for the standard JSSE cipher suite names, and the "Java Cryptography Architecture Oracle Providers Documentation" for the cipher suite names supported by the SunJSSE provider.

Note that the actual use of enabled cipher suites is restricted by algorithm constraints.

Note also that these system properties are currently supported by the JDK Reference Implementation. They are not guaranteed to be supported by other implementations.

Warning: These system properties can be used to configure weak cipher suites, or the configured cipher suites may become more weak over time. We do not recommend using the system properties unless you understand the security implications. Use them at your own risk.

See JDK-8162362
