The full version string for this update release is 1.8.0_221-b11 (where "b" means "build"). The version number is 8u221.
JDK 8u221 contains IANA time zone data version 2018i. For more information, refer to Timezone Data Versions in the JRE Software.
The security baselines for the Java Runtime Environment (JRE) at the time of the release of JDK 8u221 are specified in the following table:
|JRE Family Version||JRE Security Baseline (Full Version String)|
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 Bulletins. This JRE (version 8u221) will expire with the release of the next critical patch update scheduled for October 15, 2019.
For systems unable to reach the Oracle Servers, a secondary mechanism expires this JRE (version 8u221) on November 15, 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. For more information, see 23.1.2 JRE Expiration Date in the Java Platform, Standard Edition Deployment Guide.

There is a risk of breaking Java Access Bridge functionality when installing Java on a Windows system that has both a previously installed version of Java and an instance of JAWS running. After rebooting, the system can be left without the
WindowsAccessBridge-64.dll in either the system directory (
C:\Windows\System32) for 64bit Java products or the system directory used by WOW64 (
C:\Windows\SysWoW64) for 32bit Java products.
To prevent breaking Java Access Bridge functionality, use one of the following workarounds:
The goal of the workarounds is to avoid the scenario of uninstalling existing JRE(s) from Java installer when JAWS is running.
JDK-8223293 (not public)
A new boolean system property,
jdk.security.useLegacyECC, has been introduced that enables switching between implementations of ECC.
When the system property,
jdk.security.useLegacyECC, is set to "true" (the value is case-insensitive) the JDK uses the old, native implementation of ECC. If the option is set to an empty string, it is treated as if it were set to "true". This makes it possible to specify
-Djdk.security.useLegacyECC in the command line.
If the option is explicitly set to "false", the provider decides which implementation of ECC is used.
The default value of the option is "true". Note that the default value might change in a future update release of the JDK.
JDK-8217763 (not public)
Red Hat Enterprise Linux 8 no longer includes packages which provided TrueType fonts used by JDK for CJK (Chinese, Japanese, and Korean) languages.
Text display for those languages will therefore result in missing glyphs.
See JDK-8209672 for a resolution to this issue.
This release also contains fixes for security vulnerabilities described in the Oracle Critical Patch Update. For a more complete list of the bug fixes included in this release, see the JDK 8u221 Bug Fixes page.
