I've been lucky enough that the large organisations I worked for generally had policies and enforcement to ensure that all applications were kept current. It's more initial effort but it pays dividends.

But even if you don't have that, most people work on at most a handful of apps at a time, and again I would defer checking against a specific version to CI most of the time rather than switching around which JVM I'm using locally, unless your code was very tightly coupled to JVM internals somehow.
