It seems to do no difference if I add the @Singleton to PostalManager or not.
Also, I've tried both;
public class MyModule extends AbstractModule {
@Override
protected void configure() {
}
}
and
public class MyModule extends AbstractModule {
@Override
protected void configure() {
bind(PostalManager.class).asEagerSingleton();
}
}
Any other ideas as to why I get the exception ?
Thanks.
