Java and Java ecosystem are an interesting case. Looking back over the last 15 or so years of Java most orgs went through massively over complicated setups like EJB containers to slightly better spring (GWT probably deserves a mention), to much better spring boot, and now to smaller, saner frameworks such as javeline or micronaut. The language itself is leagues and bounds ahead of what it once was in java 7 and before. And of course, the all consuming drive to use every conceivable design pattern is not in style any longer. Generation has nothing to do with it, but trends have everything to do with complexity and constant change.
