Hi Just a heads up that I have been in contact with YourKit about licenses for their tool for Apache Camel committers.
They got back to me and we have a project wide license that can hold 10 installed copies. I have installed one so there is 9 left. Anyone whom is helping with this work of work is welcome to ask for a license.
