Oh I am well aware of Java's warts and you hit a few of them but they are clearly -not- performance or reliability.

Yes there are lots of things that suck about Java and the JVM but you can't in good faith argue that it's slow and unreliable.

Once it hits full stride, sure. While not a Java dev, I work with plenty of Java enterprise systems (looking at you, ElasticSearch, and probably big chunks of AWS).

One appreciates the engineering durability of it all.

I do refer to the healthy startup time for the cluster as the "Java pause".

Perhaps that's a cheap shot, blaming the language, given that we're getting rich logging and a predictable approach that makes things boring in a good way, but there you have it.

Yeah the JVM definitely makes tradeoffs that adversely affect startup time, things like autowiring DI, etc all contribute to this - it's not just the runtime. It can be slightly annoying so periodically effort is invested to make it fast again, see recent Spring Boot startup speeds which are pretty damn quick now but can be made super fast with static wiring. (all without needing to resort to CRaC or AoT)

I was really getting at the fact that you can't reasonably call something unreliable or slow when it's probably powering some of your most loved (and performant) distributed systems that your applications rely on - doubly so if you are running on AWS or GCP. If it was either unreliable or slow, let alone both it wouldn't be fit for purpose.
