Many people were frustrated with OSGi because it explicitly made modularity up front and centre, and the majority of developers didn't want to worry about it. The modularity of Jigsaw - including different classloaders for modules - is pretty much exactly the same as with OSGi. The differences are largely syntax and lack of versioning at this point.
