ImportantOpenJDK 8 is provided in Red Hat Enterprise Linux 6.6 as a Technology Preview. For details about the support available to Technology Preview features, see https://access.redhat.com/site/support/offerings/techpreview/.Red Hat Enterprise Linux 6.6 provides OpenJDK 8 as a Technology Preview. OpenJDK 8 is the open-source reference implementation of the Java SE 8 Platform Specification defined by JSR 337. This new version of the specification adds lambda expressions and default methods to the Java programming language. It also includes a new date and time API, and extends the Java programming language to allow annotations on types.Javadoc parsing is stricter in this release, which means that some javadocs created for previous versions of OpenJDK may not compile. If you must compile prior to modifying your javadocs for these changes, you can temporarily disable javadoc generation to work around these stricter requirements.Additionally, a number of methods are deprecated as of this release. See the specification for details.
- The libnl3 package provides version 3 of libnl, a collection of libraries for netlink interfaces. libnl3 provides similar functionality to libnl, but is not a backward compatible replacement for it. Therefore, as of Red Hat Enterprise Linux 6.6, libnl3 can be installed in parallel with the original libnl package.
- The opencryptoki package, which provides a PKCS#11 implementation for Linux has been updated to version opencryptoki-3.2-2.el6.This rebase includes an opencryptoki token for access to the Enterprise PKCS#11 (EP11) features of the CEX4S crypto adapter, CPACF MSA4 extensions, and architecture support for IBM® Z Series.For more details see the Security and Administration Section.

Further, it enables our customers to integrate and automate their helpdesk services with our subscription services. The capabilities of this package include:
Detailed usage information for the tool can be found in the Red Hat Customer Portal at https://access.redhat.com/site/articles/445443.
- Red Hat Access Knowledge Base article and solution viewing from the console (formatted as man pages).
- Viewing, creating, modifying, and commenting on customer support cases from the console.

- Various other support-related commands.
- Red Hat customers can use this library to easily integrate their help desk solutions and IT infrastructure with the services provided by the Red Hat Customer Portal. Further, this library will be used by and integrated into shipped products for automatic problem determination/diagnostics.The python library provided by this package is an abstraction layer that simplifies interactions with the Red Hat Customer Portal. Simply create an instance of the API by providing the necessary authorization credentials, then use the API object to interact with the Red Hat Customer Portal.Some of the interactions supported by this API include, but are not limited to, automatic diagnostic services on log files, knowledge base searching, support case creation, attaching files to support cases, viewing the status of support cases, and viewing entitlements.
- The new rsyslog7 package provides rsyslog version 7. The previous package, rsyslog, continues to provide version 5.As of Red Hat Enterprise Linux 6.6, Red Hat will focus on maintaining the rsyslog7 package, and only critical security issues will be fixed in the rsyslog package. This allows legacy projects that require version 5 to remain supported, while giving customers access to version 7, which includes performance improvements and introduces production support for structured logging.A number of packages are dependent on rsyslog and installation requires some manual steps to ensure there are no dependency issues.Red Hat recommends that you use the
yum shellcommand to upgrade, using the following steps
# yum shell > erase rsyslog > install rsyslog7 > run transaction > quitFurther information can be found in the Red Hat Knowledgebase at https://access.redhat.com/solutions/282663
