Netty example server compiled using graalvm's native-image

Introduction

An example netty based http server, that can be compiled to a native binary image using graalvm's native-image.

Quickstart

1. Download GraalVM and extract it to somewhere. Then set the JAVA_HOME environment variable to the home of it.
2. Run mvn package on the root directory of this project.
3. The native image is produced under target directory. So you could run it to start the example server.
4. Open the link and enjoy it.

Issues

• When the output server is run, the logging handler should print to console something like the following.

  Jul 18, 2019 2:49:09 PM io.netty.handler.logging.LoggingHandler channelRegistered INFO: [id: 0x45e23bb2] REGISTERED Jul 18, 2019 2:49:09 PM io.netty.handler.logging.LoggingHandler bind INFO: [id: 0x45e23bb2] BIND: 0.0.0.0/0.0.0.0:9000 Server started, will shutdown now. Jul 18, 2019 2:49:09 PM io.netty.handler.logging.LoggingHandler channelActive INFO: [id: 0x45e23bb2, L:/0:0:0:0:0:0:0:0:9000] ACTIVE

  But sometimes the output server image does not log the above output, even though the native-image settings has not changed. Still wonder why.
