Could it be a launchpad towards further JDK 7 support?

Oracle’s tool suite control centre, that monitors, manages,
profiles, and covertly eliminate memory leaks on any JVM has
recieved a huge renovation, as the company gears towards a
revolutionary voyage into the depths of Java 7.

This is the first minor update since 2010’s 4.0.1, but with the
JRockit Mission Control
, it would have to be as cohesive at
co-ordinating as a NASA hub, and offer a plethora of vital tools.
Well, JRockit Mission Control 4.1 certainly ups the ante with new
features such as:

  • Support for Oracle JDK 7 in the shape of Java SE 7 and
    also the added bonus of local management for Hotspot JDK 1.6 and
  • Support for new platforms including Mac OS X and
  • No longer in the shadows, Eclipse (3.7) Indigo and later
    versions can be run on Mission Control.
  • Support for Associating JRockit Flight Recorder File with the
    JRockit Mission Control Client on
  •  Windows. The files with
    the .jfr extension are opened in the JRockit
    Mission Control client by default when you run the following

product_install_dirbinjrmc.exe -open

  • The new DTrace Plug-in is available through the update

  • Enhancements in Management Console such as improved file
    resource operations in the Eclipse environment and zooming
    capability for charts.
  • Flight Recorder gets new features such as a better GUI editor,
    the Thread graph renders thread transition information with
    improved selection and zooming.
