Caused by: java.lang.IllegalAccessException - with modifiers "public"

[helbertrios]

CAUSE:
When trying do conversion to an object with dynamic method.

Sample:
public AssociadoTO getAssociado() {

    Associado associado = new Associado() {
        public String getNome() {
            return "Helbert Rios";
        }
    };
    associado.setId(1);


    Mapper mapper = new DozerBeanMapper();
    return mapper.map(associado, AssociadoTO.class);
}

SOLUTION:

org.dozer.util.ReflectionUtils

public static Object invoke(Method method, Object obj, Object[] args) {
Object result = null;
try {
method.setAccessible(Boolean.TRUE); // here
result = method.invoke(obj, args);
} catch (IllegalArgumentException e) {
if (e.getMessage().equals(IAE_MESSAGE)) {
MappingUtils.throwMappingException(prepareExceptionMessage(method, args), e);
}
MappingUtils.throwMappingException(e);
} catch (IllegalAccessException e) {
MappingUtils.throwMappingException(e);
} catch (InvocationTargetException e) {
MappingUtils.throwMappingException(e);
}
return result;
}

Hi @helbertrios,

thanks for a great bug-report. You're correct, Dozer doesn't seem to work with anonymous classes as one would expect. I'll merge the bugfix from @phdd and we'll release it in the next version.
