Having some trouble with a ktor app. It works all fine until I enable auto-refresh. Any idea what would cause this? ( More detail here: https://stackoverflow.com/questions/49782953/enabling-ktor-auto-reload-breaks-the-app )

Auto-refresh uses custom classloader. In my case, jackson loaded classes from different class loaders and it messed up everything.

Hmm, so some dependency that I'm using is using a different classloader. I wish there was a bit more info what's breaking this...

I fixed this by providing OverridingClassLoader class loader to the jackson

Could you elaborate on how to "provide OverridingClassLoader class loader to jackson"?

I found that adding " squash " is one example of something that leads to auto-reload not working any more..
