Problem: PDQ Java distribution is not compatible with Java 6?

These 3 kind of errors occur during the compile of the API:

The method printf(String, Object[]) in the type PrintStream is not applicable for the arguments (String) Thesis/src/com/perfdynamics/pdq PDQ.java line 379 1185383257470 50

I should try to backdate the java version to 5.
