Oracle JDK 7u40 released - security features, hardfloat ARM, Java Mission Control and more
By Henrik Stahl on Sep 10, 2013
Oracle JDK 7 Update 40 is now available. This release introduces the following new features:
- Java Mission Control. This is an advanced monitoring/diagnostics tool inherited from JRockit, now fully supported on the JDK 7. Also adds new features such as a DTrace plugin.
- Java Flight Recorder, again a feature ported over from JRockit. This is a really cool feature that enables you to record events and metrics during runtime, and then extract them at will. You can even dump all or part of the data on a user-defined alert. Eg, "Why did that transaction take more than 1 second? Give me the last 10 seconds of data in your buffer so that I can figure out what went wrong."
- Support for the Apple Retina display with Swing/AWT and JavaFX.
- A new JDK binary for hardfloat Linux/ARM, for ARM-based micro servers and development boards. Yes, this means that we now have official JDK 7 support for the default Raspbian Linux distribution for the Raspberry Pi.
- A new Deployment Rule Set feature to enable fine granular controls for execution of Applet and WebStart applications.
- Security feature enhancements for applets, JAXP and x.509 certificates.
For Mission Control, a great source of information is Marcus Hirt's blog (thanks, Marcus!).
