CoroutineExceptionHandler not executed when provided as launch context

Question

When I run this:

fun f() = runBlocking {
    val eh = CoroutineExceptionHandler { _, e -> trace(\"exception handler: $e\") }
    val j1 = launch(eh) {
            


        

Answer 1

What is your kotlinx.coroutines version? Since 0.26.0 standalone launch builder is now deprecated and You should be using GlobalScope.launch instead.

I tried your sample and after that change it worked.
