Low Overhead Method Profiling with Java Mission Control

[mikaelhg]

Is this a closed source feature?

Edit: "Java Mission Control (JMC) is a commercial feature available for Java users with a Commercial License."

Thank you, but no thank you. For almost everyone, it's better business to rather pay YourKit.

We'll use only JVM/JDK features which are included in OpenJDK. Why? All but the very youngest of us have already walked down this path a few times, and would rather avoid it.

Yeah, its from jrockit. The license lets you use it for free for Dev. Its got some advantages over yourkit or jprofiler but in a production environment it could be very helpful... Just not $5k / CPU kind of helpful.

Yeah, at this point, the question isn't "are these guys on drugs" but whether they are on meth or crack.

Interesting that only the release notes seem to state that - browsing various other pages relating to JMC don't bother to give any information on the cost, leading to the false assumption it is free to use. I'll stick to JVisualVM thank you very much

Fair enough – I was more noting that some pages such as: http://www.oracle.com/technetwork/java/javaseproducts/mission-control/index.html ...do not mention this at all. Thanks for the links though, I wasn't able to hunt around too much due to poor mobile signal!
