             Summary: Using DefautMessage() and GenericFileMessage() without 
CamelContext throw Exception
                 Key: CAMEL-12343
                 URL: https://issues.apache.org/jira/browse/CAMEL-12343
             Project: Camel
          Issue Type: Bug
          Components: camel-core
    Affects Versions: 2.20.2, 2.20.1, 2.20.0, 2.21.0
            Reporter: Farès Hassak


Hello,

I am using version 2.19.2 and try to migrate to version 2.20.2 (and then to 
2.21.0).

Using DefautMessage() and GenericFileMessage() without CamelContext throw 
Exception :
{code:java}
java.lang.IllegalArgumentException: CamelContext must be specified on: 
Message[] at org.apache.camel.util.ObjectHelper.notNull(ObjectHelper.java:342)
{code}
In version 2.20.0, I see that these constructor was deprecated and new 
contructors was introduced for this new feature 
https://issues.apache.org/jira/browse/CAMEL-11149 :

To remain better backward compatibility, i would suggest to refer the new 
constructor in deprecated contructor  :
{code:java}
 @Deprecated
    public DefaultMessage() {
        this(new DefaultCamelContext()); //use new contructor with 
DefaultCamelContext to avoid exception
    }

    public DefaultMessage(CamelContext camelContext) {
        setCamelContext(camelContext);
    }

{code}
{code:java}
    @Deprecated
    public GenericFileMessage() {
        this(new DefaultCamelContext()); //use new contructor with 
DefaultCamelContext to avoid exception
    }

    public GenericFileMessage(CamelContext camelContext) {
        super(camelContext);
    }

    /**
     * @deprecated use {@link #GenericFileMessage(CamelContext, GenericFile)}
     */
    @Deprecated
    public GenericFileMessage(GenericFile<T> file) {
        this(new DefaultCamelContext(), file); //use new contructor with 
DefaultCamelContext to avoid exception
    }

    public GenericFileMessage(CamelContext camelContext, GenericFile<T> file) {
        super(camelContext);
        this.file = file;
    }
{code}

Otherwise, the deprecated constructeur must be deleted in order to detect 
errors at compile time and not at runtime.
