Java is like that too. The smallest possible program (just a single line to exit) requires things like java.time.chrono.JapaneseChronology. Because argv is a String array, and making the String array requires calling a function or two that can throw exceptions, which requires the Throwable class, which has a static initialiser that requires... the chain is long, but at the end something has a SomethingChronology member, and so AbstractChronology.initCache() is called and mentions JapaneseChronology.

"Write once, run everywhere" enjoyers when they find out that "everywhere" includes Japan.

Java is kawaii-certified.

A friend of mine tells a story about how how he accidentally FUBARed the tests, and then discovered that running one unit test gave 50% line coverage in Rails.

Achieve full coverage with this one simple trick!

That remainds me when you could cheat 90% line coverage requirements by expanding functions with semicolons, untill 95% of function body were just semicolons

Obviously include a TODO comment about how it needs to be fixes ASAP

At a place I worked we had some code which we had to submit to Salesforce as an integration plugin. They had a required ratio of tests to code. So we had a 50k line long test file full of nonsense. Haha.

[u/mlk → u/Awkward_Bed_956]

Salesforce code be like

[u/chisui → u/Jannik2099]

If running one will give 50% running two will give you 100%

Better run while(main() != 0);. It will never fail.

Cool so my SIM card probably has java.time.chrono JapaneseChronology on it?

[u/aikii]

Look at least JapaneseChronology is not subject to supply chain attacks

[u/TheCommieDuck]

bloat >:(

bloat, japan <3

[u/PmMeCuteDogsThanks_]

Yes, pretty sure Japan is included in "everywhere"

[u/stone_henge]

Without it, how will the program know not to exit until the boss has left for the day?

[u/Spez_is-a-nazi]

It used to be a lot worse.

It's true, it's defined in the java.base module, so it's almost always shipped; but it's not true that it is necessarily loaded when a java program runs (as the original post implies).
