I have a function like this:

override fun processNewLines(lines: Array<String>) = lines.forEach { <http://logger.info|logger.info>(it) }

and it works as expected however when I change last invocation to lambda:

override fun processNewLines(lines: Array<String>) = lines.forEach { logger::info }

code compiles fine but there is a runtime error

java.lang.NoSuchMethodError: kotlin.jvm.internal.FunctionReference.<init>(ILjava/lang/Object;)V

at that line

koral: It should be

lines.forEach(logger::info)

. Notice the paren instead of a curly brace.

logger::info

itself is a function reference, so no need to wrap it inside a lambda

👌 thanks
