Reproduction steps:

Hi,the Injector inject beans in controllers,now I enhance the function for the injector.

I add a interface "injectable",and add some code in Injector:

public class Injector {

 * For now, inject beans in controllers and any classes that implements Injectable interface.
 * @param source
 *            the beanSource to inject
public static void inject(BeanSource source) {
    List<Class> classes = new ArrayList<>(Play.classloader.getAssignableClasses(ControllerSupport.class));
    for (Class<?> clazz : classes) {
        for (Field field : clazz.getDeclaredFields()) {
            if (Modifier.isStatic(field.getModifiers()) && field.isAnnotationPresent(Inject.class)) {
                Class<?> type = field.getType();
                try {
                    field.set(null, source.getBeanOfType(type));
                } catch (RuntimeException e) {
                    throw e;
                } catch (Exception e) {
                    throw new RuntimeException(e);

Don't have too much expectations. Unless the bug is really a serious "everything is broken" thing, you're creating a ticket to start a discussion. Having a patch (or a branch on Github we can pull from) is better, but then again we'll only pull high quality branches that make sense to be in the core of Play.
