Java software allows you to run applications called "applets" that are written in the Java programming language. These applets allow you to have a much richer experience online than simply interacting with static HTML pages.
Java Plug-in technology, included as part of the Java 2 Runtime Environment, Standard Edition (JRE), establishes a connection between popular browsers and the Java platform. Java allows applications to be downloaded over a network and run within a guarded sandbox. Security restrictions are easily imposed on the sandbox.
Many cross platform applications also require Java to operate properly.
IANA Data 2018e
JDK 8u201 contains IANA time zone data version 2018e. For more information, refer to Timezone Data Versions in the JRE Software.
Change: TLS anon and NULL Cipher Suites are Disabled
The TLS anon (anonymous) and NULL cipher suites have been added to the jdk.tls.disabledAlgorithms security property and are now disabled by default.
Change: jarsigner Prints When a timestamp Will Expire
The jarsigner tool now shows more information about the lifetime of a timestamped JAR. New warning and error messages are displayed when a timestamp has expired or is expiring within one year.
Java Expiration Date:
The expiration date for 8u201 is April 16, 2019. Java expires whenever a new release with security vulnerability fixes becomes available. For systems unable to reach the Oracle Servers, a secondary mechanism expires this JRE (version 8u201) on May 16, 2019. 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.
This release contains fixes for security vulnerabilities described in the Oracle Java SE Critical Patch Update Advisory. For a more complete list of the bug fixes included in this release, see the JDK 8u201 Bug Fixes page.
