YourKit has given me a free license for their profiler, which has been extremely useful. All they asked in return is that I show this:

YourKit is kindly supporting open source projects with its full-featured Java Profiler.
YourKit, LLC is the creator of innovative and intelligent tools for profiling
Java and .NET applications. Take a look at YourKit’s leading software products:
YourKit Java Profiler and YourKit .NET Profiler.

I think that’s pretty fair.
