Sure, but GP was criticizing Java, not Exceptions. I find that JavaScript, Ruby and C# are all easier to debut in practice than Java, and all three use exceptions. IMO this is mainly due to what idiomatic Java looks like and how libraries/frameworks are structured.

Hm, we've had different experiences then. My experience with languages like JS/Ruby is that exceptions are often obfuscated (for js) and will frequently be meaningless type errors like "foo is not an object". I didn't use C# but I'd guess it's similar to Java. After all, here's an exception factory library for C# (https://github.com/scionwest/ExceptionFactory https://github.com/scionwest/ExceptionFactory). What most people seem to complain about when they say "Java" is actually dependency injection frameworks, not the language or even regular libraries (which typically don't use them). I also don't like Guice so can sympathise, but DI frameworks vary in quality a lot, and you don't have to abuse them. Modern frameworks are based on code generation and check much more at compile time. My app uses a compile time DI framework to set up the build task graph, but doesn't have a factory bean anywhere and has never yielded strange errors about factories that were hard to debug.

Sure, in a platonic ideal Java codebase, it’s all great, but I am talking about my actual practical experience, and I said as much in my message.

    Yeah but I don't know if DI (ab)usage is really idiomatic Java. I've written lots of Java over the years and only rarely used DI frameworks. Libraries never use them. When I did use them they've been fairly restrained and most of the code you wouldn't notice it. It might be idiomatic if all you do is write web servers.

      Alright, that's fair! I only ever wrote web apps in Java, other than very small scripts and libraries. You're right.
