There is a public TestAction(long id); constructor there actually, so I track code into net.greghaines.jesque.utils.ReflectionUtils.findConstructor, and found this:

            if (typeDiffWeight < minTypeDiffWeight) { // right here, should be `<=` ?
                // Choose this constructor if it represents the closest match.
                constructorToUse = candidate;
                minTypeDiffWeight = typeDiffWeight;
                ambiguousConstructors = null;
            } else if (constructorToUse != null && typeDiffWeight == minTypeDiffWeight) {
                if (ambiguousConstructors == null) {
                    ambiguousConstructors = new LinkedHashSet<Constructor<?>>();
                    ambiguousConstructors.add(constructorToUse);
                }
                ambiguousConstructors.add(candidate);
            }

Start with net.greghaines.jesque.utils.ReflectionUtils.findConstructor at the reported line, then follow the stack trace through createObject and materializeJob. Reproduce the lookup using TestAction(long) with args=[6] and verify how equal type-difference weights are handled; done when the valid constructor is selected without NoSuchConstructorException.
