Unfortunately the name Glassfish has been pretty tainted by now. If you say your platform is based on Glassfish they'll automatically assume you're an old donkey not up to date on latest Java technologies like Spring Boot.
>”latest Java technologies like Spring Boot.”
Which are already old enough to drive… latest my ass.
I love the irony / (perceived) sarcasm in your comment, :p.
That's what the article is trying to deflect, isn't it?
Many people rely on vibes from the past instead of updating their knowledge with the current info. It's true that some companies in the past attempted to taint GlassFish to promote their alternative products. And there was nobody to defend GlassFish and keep it up to date.
This is different now, with GlassFish at the Eclipse Foundation, the OmniFish company behind it and providing enterprise guarantees, and GlassFish itself modernizing with fast startup, runnable JAR, support for latest Java and Jakarta EE, Jakarta Data and NoSQL databases.
