You're comparing an OS independent language to an entire operating system? I think you're probably right, I don't think there is a sane comparison. But I don't think that's what the parent was referring to. I'm not sure there are too many languages that provide (eg via slf4j or JMX) extremely customisable, universal logging and monitoring across multiple libraries that are used together in a single application. That's not a function of the language itself though, just the maturity of the libraries and ecosystem around it. Combine that with the tooling (eg IntelliJ IDEA) and no matter how much you might think Java as a language is verbose/clunky/crappy (which I tend to agree with), it's pretty hard to beat for large, complex, maintainable systems.

"You're comparing an OS independent language to an entire operating system?" No, I am not comparing Java, but JVM. JVM is a platform, so it should have insight what's happening on it, don't you think? Whether this insight comes from the platform (JVM or z/OS) or the underlying system (native host OS or mainframe) is irrelevant - you probably want both (and in z/OS you get both). Whether Java (the language) is clunky is irrelevant - z/OS has lot clunkier languages on it (application development is huge pain on z/OS compared to JVM), and I still think z/OS beats JVM for large/complex/maintainable systems. ;-) (Basically for the same reason - more mature.) z/OS has many logging and tracing functions, at different granularity, some of them are assisted with mainframe hardware. I don't see how JVM could beat it, but I may be wrong.
