I vaguely remember hearing this this was only really available for toy code and that this function created the class ignored the arguments and qualified println when you compiled it, so it wasn’t actually that useful?
Neither did Log4j in basically all cases, some maniac just put arbitrary code callbacks into their logger, undocumented and enabled by default. The insane part isn’t the feature itself it’s the fact it’s enabled by default in a logger of all things.
People in my experience are actually very serious about the standard out to debug log which is… baffling. Same people generally outright refuse to learn how to use a debugger in languages where those are pleasant
Oh I’m completely serious. The joke is that everyone does it but everyone knows not to do it. I started doing it when I first ran into problems debugging actor contexts, and never stopped.
Actually… since around Java 21, it’s just

Printing to console is often only used for toy code anyway.
Wait, how do you debug your code?
A logger? Console prints are shitty in general but especially when you have an actual logger already
You know what println never did? Run arbitrary code on my toaster.

Oh man, I thought that was one of the classic jokes :'( I am out of touch

The good printlns become logs, obviously
Beyond that, in reality you would write
logger.info()in both 99% of the time.
