Currently, I've ported a subset of java.awt to support geometry and ICC color management classes (using apache Sanselan and the sun awt source code), and trimmed out unsupported functionality from PDFBox that depends on BufferedImage and other awt native classes.
I have tested some features including:
I assume that other features still work, but I have not been focusing my efforts anywhere else.
I would be very happy if people wanted to contribute to the effort by forking and submitting pull requests to the project.
I hope that this library becomes useful to the community. Currently, it is buggy, it is missing many PDFBox features, and it likely won't compile correctly when you first clone the repository, but I think we can put together a nearly feature complete port without killing ourselves over it.
Thanks for your interest.
