Daan de Wit commented on FELIX-3812:
------------------------------------

Property injection does work, but not for constructor arguments.

I tried both versions. My code is like this:
{code:java}
@Component
@Provides
public class Hello2Command implements Command {
        private String msg;
        
        public Hello2Command(@Property String msg) {
                System.out.println("Hello2Command ctor");
                this.msg = msg;
        }
        
        @Override
        public void execute(String args, PrintStream out, PrintStream err) {
                out.println("Hello " + msg + "!");
        }

        @Override
        public String getName() {
                return "hello2";
        }

        @Override
        public String getShortDescription() {
                return "Says hello";
        }

        @Override
        public String getUsage() {
                return getName();
        }
}
{code}

> Constructor injection does not work for properties, iPOJO tries to find a
