Mario Fusco resolved DROOLS-69.
-------------------------------
Resolution: Rejected
This is not a bug, but only how spring internally works.
In your case it is trying to convert the String DRL to the ResourceType.DRL. To do that it first check if there's a custom converter registered but there isn't any. After it tries to look for a constructor of the ResourceType class having a String as an argument, but also it cannot find it and then logs that it coudn't (org.springframework.beans.TypeConverterDelegate line 198). Immediately after (line 213) it tries to do the conversion using the method attemptToConvertStringToEnum(). This last method (line 273) checks if the ResourceType class has a static field named DRL and finally succeeds in doing the conversion.
