Map option problem when value contains '=' separator (was: How to quote / escape option values)

I would like to pass a map of options into my application like: -p AppOptions="-Dspring.profiles.active=test -Dspring.mail.host=smtp.mailtrap.io"

picocli seems to get confused by the equals sign in the value. My class:

public class MyCommand implements Callable<Object> {
    @Option(names = {"-p", "--parameter"})
    @Getter
    Map<String, String> parameters;

    public static void main(String[] args) throws Exception {
        Object result = CommandLine.call(new MyCommand(), System.out, args);
        System.exit(result != null ? 0 : 1);
    }

    @Override
    public Object call() throws Exception {
        System.out.println(this.parameters.get("AppOptions"));
        return new Object();
    }
}

I expect it to output the entire value, but I’m only getting -Dspring.profiles.active. How can I escape the value correctly?

I don’t want to make AppOptions part of my CLI directly, because I don’t control the content and users should be able to pass in an arbitary set of parameters.
