@groostav Take a look at this example: https://try.kotlinlang.org/#/UserProjects/q1qp3un899nd41tcall8qmapg5/9kedig2qt02lre65kj8jt9eqan What is different from your code?

ilya.gorbunov: Oh, of course, the obvious bit. try

override fun fillInStackTrace(): Throwable{
  println(trace.lines())
}

So why can't you move that code from

fillInStackTrace

init

because I'm trying to modify the stack trace...

and I had it in my head that you can only do that from

fillInStackTrace

but thats not right, thats just a performance optimization

if I do it from init it'l cause the JVM to build the stack trace once, then over-write that result, which means I burn a little CPU time, but no other problems

or no, thats not right either, I can simply override

fillInStackTrace

to no-op, then

setStackTrace

in the init call

sorry I'm really confused with this API, thanks Ilya.
