How to debug class loading
yeah that's because my hello world isn't actually valid kotlin code 😂 I updated the demo with the new build and a bit of UI - https://f43nd1r.github.io/kotlin-compiler-cheerpj/ Not the fastest in the world, but it works! Impressive how you got that fixed so fast

How to debug class loading
Alright, I thought evaluating some kotlin would've been an impressive demo of cheerpj. Probably a bit too ambitious - at least I'm out of my depth here. I can see the kotlin compiler tries to figure out the memory layout of certain classes, I assume that's the part which is just different enough on cheerpj to not work out, but I have no idea how to debug or fix any of it. Thanks for the help either way 🙂

Continuing with chrome, I got to a stacktrace:

Looking at the source of ConcurrentLongObjectHashMap, the kotlin compiler seems to be accessing com.sun.misc.Unsafe using reflection here. Hard to tell which call exactly with no line numbers. I assume I can't turn on line numbers in cheerpj somewhere?

Oh, typical web development fun: only happens in firefox, chrome shows what you posted

How to debug class loading
Oh, that is an interesting approach - I was trying to get the embedded compiler running instead of the standalone
