> 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.
