is there anything built in to simplify snippets like this?

val myValue = try { 
	getValue() 
} catch (e: Exception) { 
	throw MyException()
}

Seems like a bad pattern in any case

yes, this code really smells

how so?

you can do something similar with Try monad and mapping Failure case, but nothing in stdlib

it's intended to be used for deserializing json and throwing an exception that will be mapped by the web server

But what is the reason to lose cause?

the main reason deserialization can fail is if the input is bad, i don't really care why, i just want to throw a BadRequestException

It’s kinda strange, I still don’t see any reasons to do that in your case and yeah, this approach is really smells. Don’t forget that deserialization can fail not only because bad input, but you catch all exceptions But your question was about somethign standard, no, there is no such thing in stdlib, you can easily write

thanks, i'll do that
