Looking over the code exposed the following bug. A client may change the predicate associated with a property. The mapping then should allow for retrieving that property by the predicate. It does not, so the following code would fail

// assuming that the property fulfills
assert property.getPredicate.equals(oldPredicate);
beanMapping.setPropertyPredicate(newPredicate);
beanMapping.getProperty(newPredicate); //<-- fails to find it.
