java2pdf ... search good lib without license restrictions (e.g., no AGPL)

I am developing a JavaFX project and I need an output of the calculation results in pdf format. I'm looking for an easy to use lib. I like iText.

1.) If you use the old version iText V2.1.7, can you use it freely?
2.) Is there a better java2pdl-lib alternative, without the whole license madness?

Sorry, I am just a small developer (only time contract) with an extremely tight project schedule. My boss will not allow me to include a cost-creating Lib into the project. So my questions about a free java2pdf lib.
