Dear Dalibor, Donald and java2d members,

I am currently working hard to improve performances of the pisces java2d
renderering engine.

To help me improving cpu hotspots, I need an efficient java profiler (lower
overhead than netbeans profiler).

I *personally* requested this morning an "open source" license for Yourkit

As you can see in the sales response (below), this license can be granted
free of charge *but it requires a public acknowledgement on the 2D Graphics
Group page of the OpenJDK web site*.

As I am only a contributor, who can decide if it is possible (dalibor,
donald) ?
What are your opinions ?

Moreover I think having such profiler could be helpful to other openjdk
projects as well. If anybody else is interested, please say it on the
discuss mailing list.

Apparently, licenses are given to persons having their names:
"Please send me the list of developers (names and surnames) who need

Best regards,

PS to Vladimir Kondratyev: I am waiting for the openjdk project manager
decision before going further.

FYI, here are the license request email followed by the Yourkit sales
