BeanUtils.populate throws an exception (INoSuchMethodException -> 
nvocationTargetException) in case the bean is a nested class:

public class BeanUtilsTest extends TestCase {
        TestBean bean = null;
        Map<String, Object> params = null;

        }
        
        public void testPopulate() {
                params.put("name", "Ivan");
                params.put("authentication", false);
                params.put("age", 24);
                try {
                        BeanUtils.populate(bean, params);
                } catch (Exception e) {
                        e.printStackTrace();
                }
                
                System.out.println(bean);
        }
        
        @Override
        public void tearDown() {
                this.bean = null;
                this.params = null;
        }

        private String name;
        
        private int age;

        public String getName() {
                return name;
        }
        
        public void setName(String name) {

        }

        public void setAuthenticated(boolean authenticated) {
                this.authenticated = authenticated;
        }
        
        @Override
        public String toString() {
                return ToStringBuilder.reflectionToString(this);
        }
