TPC-C Benchmarks For JDBC?

woggo asks: "I need to benchmark two different JDBC drivers for a research project and would like to use a standard benchmark. I was able to find this implementation of TPC-W, but that is too much of a test of the Web server to be useful for my purposes. Does anyone know of a freely-available Java implementation of TPC-C? It needs to be reasonably conformant and I need to be able to cite the results in a paper without violating a license agreement, which would seem to exclude evaluation versions of products."
