I have a weird compiler behavior when assigning local field inside a try/catch in a deftype method java.lang.IllegalArgumentException: Cannot assign to non-mutable

does it looks like a known bug ?

I'm struggling to find a minimal repro

it's not a supported case @leonoel

https://dev.clojure.org/jira/browse/CLJ-1075

try/catches can be lifted out of the immediate function body sometimes

that's it, thanks
