hey
we dont need to be almost certain, we can just look at the code :
https://github.com/netty/netty/blob/master/transport/src/main/java/io/netty/bootstrap/AbstractBootstrap.java
and
see that it is not a public ancestor. more then that, i annotated the code
and it didnt work. here is a repl dump, same as Sean did:
; nREPL 0.1.6-preview
user> (set! *warn-on-reflection* true)
true
user> (import '(io.netty.bootstrap AbstractBootstrap ServerBootstrap))
io.netty.bootstrap.ServerBootstrap
user> (def b (ServerBootstrap.))
#'user/b
user> (.channel ^AbstractBootstrap b ^Class
io.netty.channel.socket.nio.NioServerSocketChannel)
Reflection warning, NO_SOURCE_PATH:1:1 - call to channel can't be resolved.
IllegalArgumentException Can't call public method of non-public class:
public io.netty.bootstrap.AbstractBootstrap
io.netty.bootstrap.AbstractBootstrap.channel(java.lang.Class)
clojure.lang.Reflector.invokeMatchingMethod (Reflector.java:88)
user> *clojure-version*
{:major 1, :minor 5, :incremental 1, :qualifier nil}
