Answer by tsohr for JSON order mixed up

For those who're using maven, please try com.github.tsohr/json

<!-- https://mvnrepository.com/artifact/com.github.tsohr/json --><dependency><groupId>com.github.tsohr</groupId><artifactId>json</artifactId><version>0.0.1</version></dependency>

It's forked from JSON-java but switch its map implementation with LinkedHashMap which @lemiorhan noted above.
