["Arno Noordover (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CAMEL-10135?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15369282#comment-15369282 ] 

Arno Noordover commented on CAMEL-10135:
----------------------------------------

It doesn't seem to be a bug.
The creation of the bean is done by org.apache.camel.model.BeanDefinition and begins by getting the clazz on line 274.
Eventually the line 304 is executed
{code}
                        // this is only for invoking static methods on the bean
                        beanHolder = new ConstantStaticTypeBeanHolder(clazz, routeContext.getCamelContext());
{code}
My conclusion is that no instance is created because the processor is going to try and call static methods on your bean-class.
When you add the following method to your bean
{code}
        public static String doSomeBrickletThing(String hello) {
            return "Camel in your house!";
        }
{code}
you don't see any failure.

> When a Route is referring to a Java Bean by class type while that class has no default constructor, Camel should throw an exception indicating that creation of the bean failed. Instead it ignores this problem resulting in an exchange encountering a null pointer exception.
