Allow end users to choose the relaxed strong encapsulation that has been the default since JDK 9. With this change, the default value of the launcher option --illegal-access is now deny rather than permit. As a consequence, existing code that uses most internal classes, methods, or fields of the JDK will fail to run. That option will, however, be removed in a future release. JEP Warnings for Value-based Classes Users of the value-based classes provided by the standard libraries—notably including users of the primitive wrapper classes—should avoid relying on the identity of class instances.

Programmers are strongly discouraged from calling the wrapper class constructors, which are now deprecated for removal. New javac warnings discourage synchronization on value-based class instances. Log4J flaw turns into pandemic with over , attacks initiated within 72 hours. Python overtakes Java, JavaScript as most popular programming language for first time in 20 years.

The victory doesn't necessarily indicate it's the best, though. Software similar to Java SE 16 5. Java offers the rich user interface, performance, versatility, portability, and security that today's applications require. If this library is missing, then the pkg mechanism will require it during installation of the JDK. If installing the JDK by using a tar. Following the JDK's update to tzdatab, the long-obsolete files named pacificnew and systemv have been removed.

Java JDK Download. Last updated:. January 9, User rating:. The default ordered list is now: x, secpr1, secpr1, secpr1, x, ffdhe, ffdhe, ffdhe, ffdhe, ffdhe The default list can be overridden by using the system property jdk.

The main change is Palestine ends DST earlier than predicted, on The main change is Fiji starts DST later than usual, on Bug Fixes 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 The named curves are listed below.

With 47 weak named curves to be disabled, adding individual named curves to each disabledAlgorithms property would be overwhelming.

To relieve this, a new security property, jdk. To use the new property in the disabledAlgorithms properties, precede the full property name with the keyword include. Users can still add individual named curves to disabledAlgorithms properties separate from this new property.

No other properties can be included in the disabledAlgorithms properties. To restore the named curves, remove the include jdk. To restore one or more curves, remove the specific named curve s from the jdk. Curves that are disabled through jdk. As a result of this new feature, the Kerberos client can take advantage of more dynamic environment configurations and does not necessarily need to know in advance how to reach the realm of a target principal user or service.

Support is enabled by default and 5 is the maximum number of referral hops allowed. A new system property, jdk. The default value of the system property is The value of the property, which is by default not set, is a comma separated list of the mechanism names that are permitted to authenticate over a clear connection.

If a value is not specified for the property, then all mechanisms are allowed. If the specified value is an empty list, then no mechanisms are allowed except for none and anonymous. The default value for this property is 'null' i. To explicitly permit all mechanisms to authenticate over a clear connection, the property value can be set to "all". If a connection is downgraded from encrypted to clear, then only the mechanisms that are explicitly permitted are allowed.

The property can be supplied to the LDAP context environment map, or set globally as a system property. When both are supplied, the environment map takes precedence.
