Why would you compare Eclipse GlassFish instead to Payara or Wildfly/JBoss? Anyway, that bickering between JEE application server vendors is what caused Spring to win. It doesn't matter it has update churn that is almost as bad as in JS ecosystem, just the fact you don't have to think about AS helped adoption. Well that and significantly easier testing. And Spring Data with generating queries from method names. And you can't recruit people with JEE knowledge anyway, they all know only Spring.
