YourKit Java Profiler Open Source License Request

I like very much netbeans profiler and I use it since I adopted netbeans 6.
Recently (7.3) it happens sometimes that the socket connexion is lost with
the profiled application.
In pisces context, I use the bootstrap prepend option to inject my patched
classes into the openjdk jvm. Then netbeans is unable to instrument them.
Moreover, I use the instrument mode over sampling because I want accurate
method call counters and I advocate it is still difficult / obscure how to
tell netbeans which classes to instrument or set profiling points: it often
profiles nothing when I try tuning them.
If you have some time, could we talk using skype today ? I live in france

Yourkit with default settings).
