Yeah, and it shouldn't be too much to ask for. So it drives me crazy that I can't get by in Java without a full IDE. All I want is "show docs" + "jump to definition" + "show references" + "show implementations". I should not need IntelliJ for this.

The nullability wrappers in go's sql package are one of my least favourite parts of the langauge, haha. I really wish Go had proper sum types.

It's good that Java will eventually add that feature, but I was critical of Go for lacking generics all the way up until they added them. Java's backwards compatibility story isn't as strong as Go's, either. Generics, Go's biggest change ever, were fully non-breaking; meanwhile, some people are still using Java 8.
Go's attitude toward adding features is, "we don't have that & it's fine." If you want to dynamically load code in Java, you have the power to do all kinds of custom class loader magic. If you want to dynamically link code in Go, too bad. Now, I don't love this approach. My favourite language is Rust, which has features out the wazoo. It is beautiful and powerful and complicated. Go is none of those things, but it is austere and minimal and that has its own advantages. Java lacks the advantages of either.
Of course, Java is widely used no matter what I think of it, and it is boring (in the complimentary sense). At the end of the day, it's a fine choice for a project. But as I said earlier, thank god Go is boring enough that I don't have to write Java anymore.
