The latest features and enhancements to Oracle Java Development Kit (JDK) 7 include: advanced monitoring and diagnostic capabilities that enable customers to gather detailed runtime information and perform efficient data analysis, without impacting system performance; a new security policy that gives system administrators greater control over Java running on desktops; improved performance and efficiencies for Java on ARM servers and support for Mac OS X retina displays.

With the release of JDK 7u40, Oracle is continuing its work to merge the Oracle HotSpot Java Virtual Machine (JVM) and Oracle JRockit into the Oracle Java Development Kit (JDK), which will include the best features from each of these leading implementations.
* Oracle Java Mission Control and Oracle Java Flight Recorder are now available as commercial features in the Oracle Java SE Advanced product (they are freely available for download for development and evaluation purposes as part of JDK 7u40, but require the Oracle Java SE Advanced license for production use under the Oracle Binary Code License Agreement).
* Oracle Java Mission Control and Oracle Java Flight Recorder continuously collect detailed runtime information, with virtually zero overheard, from the JVM and other event producers, such as application servers. Customers can use the advanced graphical tools for profiling and after-the-fact incident analysis to rapidly understand and resolve issues and for monitoring and fulfilling service level agreements (SLAs).


Deployment Rule Set is a new security feature in JDK 7u40 that allows a system administrator to control which applets or Java Web Start applications an end user is permitted to execute and which version of the Java Runtime Environment (JRE) is associated with them. Deployment Rule Set provides a common environment to manage employee access in a controlled and secure manner.


JDK 7u40 is fully certified for ARM v7 and includes new support for "hard-float", which is designed to improve performance and responsiveness for GUI applications and Java server applications running on ARM servers. The latest release also provides new support for Mac OS X retina displays. Java will now recognize retina displays and automatically generate higher resolution graphics. JDK7 is now the default Java version for the latest generation of Oracle Fusion Middleware products
