Which is a bit misleading as far as Spring is concerned.
Spring has never been abandonware to the Java community. It is probably the most used framework for enterprise - I've seen maybe 10 jobs looking for Spring experience vs the JEE crap that it has mostly replaced.
I know it gets a bad view on HN - a lot of FactoryBuilderFactoryBeans and a rather large kitchen sink of APIs.
But the framework itself is well written, great docs, lots of resources.
I've been involved in a dozen different projects where the architects hated Spring and instead went to some newer hipper lang like Flask, Django, Rails, Finatra / Finagle. Spring has a learning curve, but once you get it, it is far more powerful and stable than any of these alternatives.
