Once you start with that goal, all the compromises and quirks make more sense.
So it does seem capable of leading to reasonable results on the eventual timescale, despite various inconveniences and tradeoffs along the way. Of course, lots of terrible software has certainly been written in Java too, so it's not fair to compare Java's cream of the crop with some random PyPI package and draw conclusions.
Hence the vastly different experience between Java-exposed-as-app and Java-exposed-as-webapp.
Also, this reads as unnecessary snide. Having a language that makes it easy to onboard new people is a major strength. A lot of Golangs success is attributed to that strength of the language.
And it's snide and isn't.
There's a lot to be said of being able to shovel programmers into a furnace and produce something functional. Decreasing risk to timeline and of failure makes large project PMs very happy. And generally makes stakeholders happy, because things don't outright fail as often.
I assume you're referring to Oracle here, but Oracle didn't invent Java either. Java came out of Sun Microsystems, whose color scheme seems to shift between blue and purple, so "big violet?" Just doesn't have the same ring to it.
Just stay away from Spring, and you can have a nice development experience.
