It depends on the culture of the language community for the most part. In Java community there is always the care to make things compatible to older versions in Java language itself. It is rare, as far as I know, to have any serious problems when you update from one version to another, although caution is always necessary. For frameworks, the same mindset generally applies, at least for the major frameworks I generally use, Spring at the top of the list, it has 15 years and I think it aged well. In Java there are many standards that are just implemented by various frameworks, so jump from one to the other is not very hard.
I don't see Spring going anywhere as far as web development goes, but if another new shiny framework comes, it will not be very hard the transition by what I know of how things work in Java.
