   @ijuma I'm following your work here.  Just thought I'd share what I see.
   
   I was able to get a functioning native-image broker by putting the native-image config files in the resources folder in the core project:
   ```
   core/src/main/resources/META-INF/native-image
   drwxr-xr-x    - rspurgeon 28 Feb 13:32 core/src/main/resources/META-INF/native-image
   .rw-r--r-- 1.2k rspurgeon 28 Feb 13:39 ├── jni-config.json
   .rw-r--r--   33 rspurgeon 28 Feb 13:39 ├── proxy-config.json
   .rw-r--r--  11k rspurgeon 28 Feb 13:39 ├── reflect-config.json
   .rw-r--r--  177 rspurgeon 28 Feb 13:39 ├── resource-config.json
   .rw-r--r--  166 rspurgeon 28 Feb 13:39 └── serialization-config.json
   ```
   
   and then running: 
   `./gradlew clean core:nativeImage`
   
   This ran for me:
   ```
   ./core/kafka.kafka ./config/raft-combined.properties
   SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
   SLF4J: Defaulting to no-operation (NOP) logger implementation
   SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.
   ```
   and I could connect a client to list topics.  I do get a SIGINT exception when trying to shutdown the broker from the cli with ctrl-c.
   
   I also turned on --verbose for native-image so I could verify it was reading the configs.
