Just so people know. I do not know whether there are any interesting new features as in update 40.

After installing JDK 7u45 I saw I have Java Mission Control in my Windows start menu. Looks like an interesting tool for monitoring Java programs. I haven't used it myself.

Is that the same program which was available under update 40 but you thought you had to pay extra for?

In the past, BEA Systems, the company that originally created Weblogic (a Java EE server), had their own JVM called JRockit. It had some features that Oracle's JVM didn't, such as more possibilities to capture what exactly was happening in the JVM (they called this Flight Recorder).

A few years back, Oracle acquired BEA Systems and integrated a number of features from the JRockit JVM into their own JVM. As far as I know, you could use things such as Flight Recorder only when you paid Oracle for a license. It looks like they are now opening this up and adding it to the JDK for everyone to use, without needing a commercial license.

JRockit JVM was really nice specially with Flight Recorder. It has something, as far as I remember, called "black box" that saves information continuously, which can later analyzed for any performance issues. It is nice if they are opening it up and adding it to the JDK.
