All of these, except maybe Java, brought some real good to the table. There were a variety of side-trends that never really got off the ground, at least as silver bullets, like 5GLS, whatever they are.
Java has been my primary language for the sixteen years (yes, I'm old) I've been engineering professionally. Yes, there are things I would change about it if I had the power but overall I think it's great and I love it. If I could write in Java for the rest of my life I would die a happy man.
So yes, I would say it's brought a hell of a lot of good. A lot of mission critical (and I mean critical) infrastructure at the company I work at (that you've heard of) is written in it.
