AmbiguousMethodCallException when using auto-generated classes

["LANGER Manuel (ICS460-BAI.ext)" <Ma...@spar-ics.com.INVALID>]

Hi,



using the following auto-generated classes (Class1, Class2) causes an AmbiguousMethodCallException in a unit test, although the mentioned methods are not ambiguous. Class1 looks like this:



@javax.annotation.Generated…

public class Class1 {



  @JsonProperty("data")

  private Class2 data = null;



  public Class1 data(Class2 data) {

    this.data = data;

    return this;

  }



  public Class2 getData() {

    return data;

  }



  public void setData(Class2 data) {

    this.data = data;

  }

}



I did not find a way to get rid of the auto-generated method “public Class1 data(Class2 data)”, so I checked why this exception is thrown in Camel.



org.apache.camel.component.bean.AmbiguousMethodCallException: Ambiguous method invocations possible:

public Class2 Class1.getData()

public Class1 Class1.data(Class2)


Obviously these two methods have different return types and different parameters, so there should not be an ambiguous method invocation possible here.

I think the problem is in class org.apache.camel.component.bean.BeanInfo in the following method:

private List<MethodInfo> getOperations(String methodName) {
        // do not use qualifier for name
        if (methodName.contains("(")) {
            methodName = StringHelper.before(methodName, "(");
        }

        List<MethodInfo> answer = operations.get(methodName);
        if (answer != null) {
            return answer;
        }

        // now try all getters to see if any of those matched the methodName
        for (Method method : methodMap.keySet()) {
            if (isGetter(method)) {
                String shorthandMethodName = getGetterShorthandName(method);
                // if the two names matches then see if we can find it using that name
                if (methodName != null && methodName.equals(shorthandMethodName)) {
                    return operations.get(method.getName());
                }
            }
        }

        return null;
    }

Here, the method “data” is mapped to the (already known) method “getData” without considering return values or parameters of these methods (only the name is compared).
