To avoid error with native image:

Caused by: java.lang.IllegalArgumentException: Class NioSocketChannel does not have a public non-arg constructor

Tested in https://github.com/danielkec/helidon/tree/native-webclient-test

helidon/examples/webclient/standalone$ mvn clean package -DskipTests -Pnative-image
helidon/examples/webclient/standalone$ sudo ./target/helidon-examples-webclient-standalone

Then call GET at: WEB server is up! http://localhost:41549/greet/test

⚠️ sudo is needed because native image is using different tmp folder, see oracle/graal/issues/1754:

Path tempPath = Files.createTempFile("helidon-large", ".tmp");
System.out.println("TEMP FILE>"+tempPath.toAbsolutePath().toString());
// ---- java -jar ---- 
TEMP FILE>/tmp/helidon-large7670469747246904903.tmp
// ---- native image ----
TEMP FILE>/var/tmp/helidon-large7964339000716791151.tmp

This reverts commit 3cdf5fe.

Hmmm, a revert of a revert.. those are always tasty.

Original revert was motivated by the appearance of helidon-io/helidon#1722 in the Helidon test case.  Thing is
this can't be reproduced in non-Helidon contexts with the same GraalVM version.  And it's definitely the case that a no-arg
constructor is present (see
https://github.com/netty/netty/blob/netty-4.1.60.Final/transport/src/main/java/io/netty/channel/socket/nio/NioSocketChannel.java).
So... this looks to be something unique to Helidon.
