Java SE 7 Update 11 Released

Oracle has released Java SE 7 Update 11, containing important security fixes. See Oracle Security Alert CVE-2013-0422 to learn more. Oracle strongly recommends that all Java SE 7 users upgrade to this release. Read the Release Notes for additional details about this release. Download Java SE 7 update 11.

A user may control, via the Java Control Panel, the level of security that will be used when running unsigned (also called "untrusted" or "sandboxed") Java apps in a browser. The user may select from five levels of security. See the "Setting the Security Level of the Java Client" documentation to see what the settings do and how users can tighten security. You can also read Henrik Stahl's blog Oracle JDK 7u10 Released with New Security Features.

Because this is an out-of schedule release remediating security vulnerabilities, going forward Oracle will increment the release number for all subsequent Java 7 releases by two numbers in order to continue having CPUs as odd numbers and limited updates as even numbers. For example, the next Java CPU release, scheduled for Feb 19, 2013, the JDK 7 release version will be renamed to Java SE 7u13.

Spotlight on JavaFX

In three interviews, veteran JavaFX developers Jim Weaver, Gerritt Grunwald, Pär Sikö and Martin Grunnarsson describe their JavaFX journey and their favorite JavaFX features.


Jim Weaver likes to call himself a “Java Technology Activist”. His three top JavaFX 2.2 features are deployment on Linux, Mac OS, Windows and ARM devices, Web View control and native installer running on user’s machine. He is also the editor of the JavaFXcommunity.com. This website “aggregates and provides a common place where JavaFX developers can find resources (downloads, APIs and real world examples) and a blog and twitter feeds.”


Gerritt Grunwald is a software engineer, working on interfaces and UI controls at Canoon Engineering AG. “I use 100% JavaFX today” and “I try to evangelize everybody to use JavaFX”. Gerritt sees great opportunities for JavaFX on embedded devices such as displays at airports or train stations. He presented a demo on how to create JavaFX controls on a BeagleBoard.


Martin Gunnarsson is a designer and front-end developer at Epsilon and Pär Sikö is a Java front-end developer at Jayway. Both JavaFX developers, they are convinced that “we have a very powerful WebView in JavaFX 2”. Their presentation was about how to bring web content into a JavaFX application and how to set up two-way communications between the Java and JavaScript code running in WebView. Their presentation called JavaFX Mashups is available online on JavaOne website.

Java Experts on the State of Java

In a new article by yours truly, now up on otn/java, titled “Java Experts on the State of Java,” four Java experts, Adam Bien, Charles Nutter, Kirk Pepperdine and Simon Ritter, share their unique perspectives on what’s happening in the world of Java.

Consultant Adam Bien, winner of many awards and an expert in Java EE, remarks that, “Only a few years ago, Java EE was used mostly by larger companies—now it becomes interesting even for one-person shows.” He is also excited about Project Nashorn, which is coming in Java SE 8.

Charles Nutter, co-creator of JRuby and a Java Champion, observes that “JRuby seems to have hit a tipping point this past year, moving from ‘just another Ruby implementation’ to ‘the best Ruby implementation for X,’ where X may be performance, scaling, big data, stability, reliability, security, or one of several other features important for today’s applications.”

Java Champion Kirk Pepperdine, an expert in Java performance tuning, comments that, “The volume of data we’re dealing with just seems to be getting bigger and bigger all the time. A couple of years ago, you’d never think of needing a heap that was 64 GB, but today there are deployments in which the heap has grown to 256 GB, and there are plans for heaps that are even larger. Dealing with all that data simply requires more horsepower and some very specialized techniques. In some cases, teams are simply trying to push hardware to the breaking point. Under those conditions, you need to be very clever just to get things to work—let alone to get them to be fast. We are very quickly moving from a world where everything happens in a transaction to one in which you’ve lost if you even consider using a transaction.”

Finally, Oracle’s Java Rock Star Simon Ritter celebrates the Raspberry Pi: “I don’t think there is one definitive thing that makes the Raspberry Pi significant, but a combination of things really makes it stand out. First, it’s the cost: $35 for what is effectively a completely usable computer. OK, so you have to add a power supply; an SD card for storage; and maybe a screen, keyboard, and mouse, but this is still way cheaper than a typical PC. The choice of an ARM processor is also significant, because it avoids problems such as cooling (no heat sink or fan) and can use a USB power brick.”

Top 10 Java Stories of 2012

2012 was a good year for Java. The platform moved forward in many ways and on new platforms. Several Java update releases came out throughout the year, good progress was made toward upcoming releases, and the Java community continues to inspire. Here are our topic Java stories of 2012:

Java and JavaFX on Mac OS from Oracle
Java SE 7 Update 4 was the first time Oracle delivered both the JDK and JavaFX SDK for Mac OS X. The Mac OS JDK (which will include the JavaFX SDK) is available for download from the Oracle Technology Network download page.

JavaFX Continues Open Sourcing
Regular code drops of JavaFX 2.0 source code were made public on OpenJFX throughout 2012. You may have missed that this was happening because it felt so natural and right.

Java for Embedded Resurgence
Cisco predicted that there will be 50 billion web-connected devices in the year 2020. Whatever the number, it's a huge opportunity, and developers are leveraging their Java skills to talk to embedded devices. In 2012, Oracle hosted the first Java Embedded @ JavaOne event. Developers showed lots of interest in Raspberry Pi, a small "computer on a board." Also, Oracle announced a new product, Oracle Java ME Embedded 3.2, a complete client Java runtime optimized for resource-constrained, connected, embedded systems. Small is getting big!

Project Nashorn is Open Sourced
Oracle open sourced Nashorn, the JavaScript engine, and made the source available on OpenJDK.

Project Jigsaw: Late for the Train
Java SE 8 (JSR 337) Expert GroupJava SE 8 (JSR 337) Expert GroupAfter due consideration, the Java SE 8 Expert Group agreed with Chief Architect Mark Reinhold that Project Jigsaw should be deferred to Java SE 9. They agreed that there would not be enough time in the Java SE 8 schedule for the broad evaluation, review, and feedback that such a profound change to the Java platform would require. 

Steady Progress on Java EE 7
Work progressed on Java EE 7 under JSR 342, including the support for HTML 5 in the form of Web Sockets and JSON-P; the simplified JMS 2.0 APIs; improved Managed Bean alignment, including transactional interceptors; the JAX-RS 2.0 client API; support for method-level validation; a much more comprehensive expression language; EJB 3.2, and more.

Adopt a JSR Increases Community Involvement
Realizing that getting involved in JSR development earlier is better for everyone, community members took it upon themselves to create an Adopt a JSR program. JUGs and individuals are now monitoring and providing feedback several JSRs. (You can too!)

Java Community Process (JCP) Merged Executive Committees
As part of the JCP.Next effort, the second JSR as part of the JCP program reforms, JSR 355, EC Merge, took effect. JCP 2.9 merged the two Executive Committees (EC) -- one representing Java SE/EE and one representing Java ME--into one EC.

Java Rock Stars Join Oracle
Several Java technology luminaries joined Oracle, including JavaFX experts Stephen Chin and Jim Weaver, and Java EE gurus Reza Rahman and Bruno Borges.

Six New Java Champions
The new Java Champions of 2012 were recognized for their contributions to the Java community: Agnes Crepet, Victor Grazi, Yara Senger, Martijn Verburg, Lars Vogel, and Johan Vos. They also jumped right in with their feedback and ideas.

2012 was the right mix of code, corporation, and community for Java.
