Quarkus Master - Classes that should be initialized at run time got initialized during image building

[jamesnetherton]

I observed some failures building camel-quarkus with the latest Quarkus 999-SNAPSHOT.

This happens on at least the HTTP and Telegram native tests. Given this is related to Netty, it's likely it fails for other extensions too.

I don't know if this is the culprit but there's a number of io.netty.util.concurrent classes here: https://github.com/AsyncHttpClient/async-http-client/blob/master/client/src/main/java/org/asynchttpclient/netty/channel/ChannelManager.java
