A new Java project is as pristine as a new Go project
The problem is that most Java developers have become so familiar with and attached to bloated frameworks that they simply aren't interested in trying any other way. They have a lot of time and effort invested into mastering these frameworks. "Let's use Spring for that", and endless talk of the "persistence layer" for even the most basic apps.
More like 90% blindly advocating the superiority of Java. Does he ever sleep?
Go is particularly well suited to long-running critical server apps. It has fewer GC issues compared to Java and is also simpler language (making it harder to screw things up - Java generics can get very complex).
Many of the Java monitoring is only critical because of the garbage collection issues with large heaps. Since switching away from Java we don't miss any of the features you've listed. The problem with Java is the mountain of bloated frameworks which have become standard over the last 10+ years - things like Spring, Hibernate etc. which new developers are expected to learn. With Go new developers which join the team aren't saddled with years of legacy frameworks which are expected as standard knowledge. The JVM is a great platform, but Java the language and to a greater extent its frameworks are a major liability for the future of the JVM. Go and Java (the language) are both incredibly boring to program in (a good thing in if you have developers of varying skill levels), but they are a safe choice with a low bar for learning. Java unfortunately has a mountain of legacy cruft which makes it a pretty terrible choice for new hires to ramp up on.
