Hot-reloading doesn't work if there are multiple ebean datasources

[thomasguo]

When we put 2 or more ebean datasources in an application, the hot-reloading doesnt work. For example:

In application.conf :

## default dataSource
db.url = "jdbc:mysql://127.0.0.1:3306/star-web?useUnicode=true&characterEncoding=utf8"
db.user = xxxxxx
db.password = xxxxxx
## another dataSource
centreDB.url = "jdbc:mysql://127.0.0.1:3306/star-centre?useUnicode=true&characterEncoding=utf8&databaseName=centre"
centreDB.user = xxxxxx
centreDB.password = xxxxxx

In startup MyApp.java :

{
        //.....
        use(new Ebeanby().doWith((ServerConfig cfg) -> {
            cfg.addPackage("xxx.star.web");
        }));
        use(new Ebeanby("centreDB").doWith((ServerConfig cfg) -> {
            cfg.addPackage("xxx.star.centre");
            cfg.setDefaultServer(false); 
        }));
        //.....
        get("/", (req) -> "Hello World!");
}

And start the application with 'mvn clean jooby:run' . If change any code, the hot-reload begins and throw an exception like following:
