Why

SerializationException

is marked as

SwallowedException

? Even being open,

public open class SerializationException : IllegalArgumentException

, the child exceptions are

internal

. Should I file a feature request for this as it is the kotlinx serialization library?

I'm not too familiar with that exception. Is it usual to catch it and just provide a default value? For example, you should catch

MalformedURLException

to know if an String is a well-formed URL.

I can't catch further than

SerializationException

as the nested classes are internal, that is the most specific one. I understand the part of being agnostic, but at the same time even serialization library being outside of stdlib, I think detekt should try them as official libraries in a way to react to them specifically, but that can be a hard work as there are tons of kotlinx libraries too...

ShallowedException

doesn't complain about you catching the exception itself. It will complain even if you could catch the more specific ones. It's complaining that you are catching it and you aren't doing anything with it.

Oh that explain all, thanks!
