Example for a custom activation strategy that combines two existing strategies

UserClientIpActivationStrategy.java

public class UserClientIpActivationStrategy implements ActivationStrategy {

    private final ActivationStrategy userStrategy = new UsernameActivationStrategy();

    private final ActivationStrategy ipStrategy = new ClientIpActivationStrategy();

    @Override
    public String getId() {
        return "user-ip";
    }

    @Override
    public String getName() {
        return "Username & Client IP";
    }

    @Override
    public boolean isActive(FeatureState featureState, FeatureUser user) {
        return userStrategy.isActive(featureState, user) &&
            ipStrategy.isActive(featureState, user);
    }

    @Override
    public Parameter[] getParameters() {
        return new Parameter[] {
                userStrategy.getParameters()[0],
                ipStrategy.getParameters()[0]
        };
    }

}

how do we do this in property file, i mean how about this
FEATURE_02=true

FEATURE_02.strategy=user-role,username --- this is not working
FEATURE_02.param.roles=roleb
FEATURE_02.param.users=chkal,john
