Oracle JRockit Mission Control 3.1 Available!

Finally! The new version of JRockit Mission Control is out! It features a much improved user interface, new extensibility features and an experimental update site that will go on-line as soon as we get the go from legal.

Hope you’ll like it! :)

You can download it from the JRockit Mission Control Home Page, either as a stand alone application, or as a set of Eclipse plug-ins that can be run in 3.3 or 3.4 versions of Eclipse.

Here is a minimalistic list of what is new:

There is also a set of neat experimental plug-ins that will be published as soon as we get the go ahead from legal. The first release of the Experimental Update-site will (at least) contain:

  • PDE Wizards for creating plug-ins for JRockit Mission Control
  • A JConsole Plug-in Plug-in which lets you run JConsole plug-ins inside JRockit Mission Control
    (It is, IMHO, a much better idea to convert them to true JRMC plug-ins though. ;) I just implemented that plug-in for fun.)

For more detailed information about the 3.1.0 release, please check out the “New and Noteworthy” page introduced with this release.
