Hello,
I can't get JPA + Guice + Eclipselink to work. I've tried all solutions
available, but this might be a bug:
@Override
protected void configure() {
install(new JpaPersistModule(PERSISTENCE_UNIT_NAME));
final MyInitializer initializer = new MyInitializer();
requestInjection(initializer);
initializer.go();
System.out.println("next");
install(new DaoModule());
}
private static class MyInitializer {
@Inject
public PersistService service;
public void go() {
System.out.println("OKAY 1");
service.start();
System.out.println("OKAY 2");
}
}
Prints:

eagerly.
Bug?
