Red Hat already supports OpenJDK on its own Enterprise Linux (RHEL) platform.

Red Hat will support its Windows distribution of OpenJDK, an open source version of standard Java that has been in beta for about a year. Red Hat’s OpenJDK distribution supports Java 11 and Java 8 for production workloads.

The support services for Windows range from patches for high-priority security vulnerabilities to helping businesses develop Java applications.

Different levels of support will be available, based on service-level agreements and on the number of workstation and server cores, but Red Hat would not disclose its pricing.

In June 2018. Oracle moved to a subscription model for commercial-level Java support instead of a perpetual license and an annual support fee.

Oracle has contributed 100 percent of EE and GlassFish application server components to the foundation. GlassFish has served as a reference implementation of Java EE, which has been renamed Jakarta EE under Eclipse’s jurisdiction. The foundation said that it now had all the components in hand, which have been published to GitHub repositories. What this means is progress of the individual projects under Eclipse’s enterprise Java effort now is largely under control of the projects themselves.

The foundation also noted several other milestones that have been reached in the past couple of weeks:

Java EE Technology Compatibility Kits (TCKs) have been contributed and now are available in open source. This move provides transparency in that vendors, customers, and the community now can see actual tests being performed and gain insight into the process.
Eclipse will be able to ship Eclipse Glassfish as Java EE 8-compatible.
Builds for Enterprise Eclipse for Java (EE4J) projects now are running on Eclipse infrastructure. EE4J the is open source initiative for enterprise Java at Eclipse.
IBM, Oracle, Payara, Red Hat, and Tomitribe have committed to three years of funding for Jakarta EE, ranging from $25,000 to $300,000 each per year. This will fund creation of a dedicated team and marketing activities.

Ecilpse agreed to take jurisdiction over enterprise Java last year, after Oracle sought to divest itself of the platform and turn it over to an open source organization.

Currently, repos for the OpenJDK project are on an Oracle-hosted Mercurial server. But Project Skara, which is an ongoing effort to examine new infrastructure for OpenJDK, could have the repos moving over to Git-based repos, including possibly GitHub or other host.

If development of standard Java moves to GitHub, developers would have at their disposal a lot of tools for automation. Such a move also could be useful for Java developers working on projects besides the JDK (Java Development Kit), said Georges Saab, chair of the OpenJDK governing board and vice president of software development in the Java platform group at Oracle.

By using GitHub, developers would have access to familiar resources being used to develop the JDK itself. Microsoft-owned GitHub’s management, meanwhile, is interested in becoming a tool used in the enterprise, he added.

A decision to move would be made in the OpenJDK community, Saab said. It could happen in the timeframe of JDK 12, which is due in March 2019, or possibly afterward.

By moving OpenJDK to GitHub, OpenJDK would be in company with the enterprise variant of Java. Oracle’s Java Enterprise Edition (EE) repos already had been hosted on GitHub. That project has since been succeeded by Jakarta EE at the Eclipse Foundation. But it, too, can be found on GitHub.

The open source Corretto distribution of OpenJDK currently is in beta. It is multiplatform and can be deployed in the cloud, on premises, and on a user’s local computer. Licensed under the Gnu Public License Version 2, Corretto is designed as a drop-in replacement for all Java SE (Standard Edition) distributions, unless users are using features not included in OpenJDK.

Amazon touts assurances of free, long-term support for Corretto, in contrast to Oracle’s paid support for businesses to use Java SE, Amazon promises security updates distributed for free for Corretto 8 until at least June 2023, with quarterly updates. Aside from security updates, patches will cover performance enhancements, garbage collection scheduling, monitoring, and prevention for out-of-memory situations. Reporting and threat management also will be covered by the patches.

Corretto 8 currently provides the features in 2014’s OpenJDK Version 8 (not the current OpenJDK 11), whereas Oracle’s JDK has been updated several times since. The future Corretto 11 version will support OpenJDK 11's features by fall 2019, Amazon says. It also intends for Corretto to become the default OpenJDK variant on Amazon Linux 2 next year.
The Corretto 8 beta is available for Amazon Linux 2, Microsoft Windows, MacOS, and Docker images. A production version is planned by spring 2019, with the addition of support for Ubuntu Linux and Red Hat Enterprise Linux.
When Corretto binaries are installed on a host and invoked to run applications, existing command-line options will continue to work. Amazon has run the Java Technology Compatibility Kit (TCK) on Corretto releases to ensure Java SE compatibility.

What’s new in NetBeans 10

Key to NetBeans 10 is enhanced support for Java Development Kit (JDK) 11 as well as capabilities for PHP and the JUnit 5 testing framework for Java.

For JDK 11, which arrived in September 2018, NetBeans 10.0 supports dynamic class file constants, which broadens expressivity options for language designers and compiler implementors. Other capabilities for JDK 11 include:

Local-variable syntax support for lambda parameters, to align the syntax of a formal parameter declaration in an implicitly typed lambda expression with the syntax of a local variable declaration.
Code completion for var lambda parameters.
Removal of Corba modules.
Integration with the nb-javac project to support JDK 11. The project has long provided a patched version of javac Java compiler for the NetBeans Java editor.

For PHP, NetBeans 10 lets developers add trailing commas in function calls under PHP 7.3. Developers also can use the list reference assignment as well as flexible heredoc and nowdoc syntaxes. Its PHP 7.2 support includes trailing commas in list syntax, coloring for object types, and PHP version in project properties. For PHP 7.1, NetBeans 10 adds support for class constant visibility as well as multicache exception handling, nullable types, and coloring for the void and iterable keywords. The context-sensitive lexer from PHP 7.0 is supported as well.

Java Card is a software technology providing isolation between secure hardware and software services. Typical hardware platforms that use Java Card include embedded secure elements, smart card chips, and secure systems with a general-purpose CPU. Sensitive materials such as cryptographic keys can be provisioned. The development kit is free, but manufacturers using Java Card must get a paid commercial license to use the technology.

Java Card 3.1 enables development of security services portable across a range of IoT security hardware. An extensible I/O model lets applications exchange data directly with connected peripherals over a variety of physical layers and application protocols. The new version also introduces APIs and updated cryptography functions to address IoT security and assist with design of security applications, including device attestation.

Java Card 3.1’s extended file format simplifies application deployment, code upgrade and maintenance. API enhancements improve developer productivity and memory efficiency of applications.

Java Card 3.1 introduces four security services:

A certificate API to manage trusted keys for resource-constrained devices.
A key derivation API, to protect sensitive data.
A monotonic counter API to avoid replay attacks.
A system time API for timestamping
