Jokes aside, nothing wrong with rewriting in Java. It is well-suited for this kind of thing.
Rewriting it in anything without fully understanding the original code (the fact they think 150yo are collecting benefits tells me they don't) is the biggest mistake here. I own codebases much smaller than the SSA code and there are still things I don't fully understand about it AND I've caused outages because of it.
Non programmer but skilled with computers type guy here: what makes Java well suited for this?
This is probably an incorrect prejudice of mine, but I always thought those old languages are simpler and thus faster. Didn’t people used to rip on Java for being inefficient and too abstracted?
Last language I had any experience with was C++ in high school programming class in the early 2000s, so I’m very ignorant of anything modern.
I am a programmer but I'm not sure why people think Java is suited for anything, especially a system so sensitive to bugs. It's so hard to write high quality readable code in Java. Everything is way more clunky, and verbose than it needs to be.
Some major improvements were made with versions 17+ but still, it feels like walking through mud.
It's a language from the 1990s for the 1990s.
Btw the performance is actually pretty good in Java, the old reputation for slowness is entirely undeserved today.
If it has to be JVM, then Kotlin. Java done properly.
I wish Java was declared deprecated back in 2017 when Kotlin was adopted for Android and supported by Spring. It was the only sensible way forward for JVM. Sure with containerization there's some debate for the necessity of JVM at all but its GC and runtime optimizations are nice.
Java has still an enormous adoption, though. It'd be very self harming making it deprecated. And I don't think containerization solves majority of cases, perhaps it does it better in backend. So both GC and Java are here with us like forever 🤷♂️
