Compatibility with GraalVM Native Image

[DarkAtra]

It would be awesome if this lib would provide hints for GraalVM so that users can create native images of their application. E.g.: https://www.graalvm.org/22.1/reference-manual/native-image/BuildConfiguration/#embedding-a-configuration-file

So far it seems like the following runtime reflection hints are enough to allow for calls to SourceQueryClient#getInfo, SourceQueryClient#getPlayers, SourceQueryClient#getRules and SourceQueryOptions.builder().build():

META-INF/native-image/com.ibasco.agql/async-gamequery-lib/reflect-config.json:

[
  {
    "name": "com.ibasco.agql.core.util.ConnectOptions",
    "allPublicFields": true,
    "allPublicConstructors": true
  },
  {
    "name": "com.ibasco.agql.core.util.FailsafeOptions",
    "allPublicFields": true,
    "allPublicConstructors": true
  },
  {
    "name": "com.ibasco.agql.core.util.GeneralOptions",
    "allPublicFields": true,
    "allPublicConstructors": true
  },
  {
    "name": "com.ibasco.agql.core.util.HttpOptions",
    "allPublicFields": true,
    "allPublicConstructors": true
  },
  {
    "name": "com.ibasco.agql.protocols.valve.source.query.SourceQueryOptions",
    "allPublicFields": true,
    "allPublicConstructors": true
  }
]

The above config is required as Option#create uses reflection to find the declaring class, OptionBuilder#<init> uses Class#newInstance and Option#initialize loops over all fields declared in each Option class to invoke each fields getter.

Netty already supports GraalVM via https://github.com/oracle/graalvm-reachability-metadata/tree/master/metadata/io.netty

I tested it partially on MacOS (x86_64) and Windows (x86_64) via DarkAtra/v-rising-discord-bot#63. There seems to be an issue on Linux (x86_64) but i'm not sure if it's related to this project or to netty (i'm still investigating).

Thank you for this. I haven't had the chance to test this fully (computer broke down last week). Will provide further feedback once I get things up and running again.

@ribasco Could you release the new version of the lib? :D
