Disclaimer: This joke will be lost in translation but I can't help but make it

In my country, you can use the phrase "it's not beans" to describe something difficult eg "that ielts exam no be beans". Given my recent woes with spring boot, I can also say "spring webflux no be beans". But it's funny to me because the framework calls objects bound to the container "beans" so it's a nerdy, don't leave me joke
