Victor, Just a quick guess. The codebase was switched to Java7, and the IB library was also switched to a library that was compiled with Java7 The class file version for Java 7 is 51, this is the basis for my guess. My guess is your JAVA_HOME points to a java6 implementation.
If my guess is right, your easiest path is to switch to Java7 for jbooktrader. Let me know if you need help on any platform (except Windows).
