Another one? (Score 4, Informative)

According to Wikipedia there are already quite a few projects doing DbC:

Java, via iContract2, Contract4J, jContractor, Jcontract, C4J, CodePro Analytix, STclass, Jass preprocessor, OVal with AspectJ, Java Modeling Language (JML), SpringContracts for the Spring framework, or Modern Jass, Custos using AspectJ,JavaDbC using AspectJ, JavaTESK using extension of Java.

Do we really need an entirely new one? If none of those are sufficient, why not build on top of and improve an existing project? Starting over is not always a good thing...
