> NPE on DefaultMessage setBody if deprecated constructor was used
> ----------------------------------------------------------------
>
> Key: CAMEL-11948
> URL: https://issues.apache.org/jira/browse/CAMEL-11948
> Project: Camel
> Issue Type: Improvement
> Components: camel-core
> Affects Versions: 2.20.0
> Reporter: Thomas Papke
> Priority: Minor
> Fix For: 2.21.0
>
>
> After upgrade camel 2.20.0, some operations fail with a NullPointerException:
> {code}
> Caused by: java.lang.NullPointerException
> at
> org.apache.camel.impl.MessageSupport.setBody(MessageSupport.java:122)
> {code}
> The issue seems to be introduced with the change CAMEL-11380.
> The issue could be easily reproduced by using the deprecated constructor,
> where no camelContext is set:
> {code}
> Message message = new DefaultMessage();
> message.setBody("something");
> {code}
> To remain better backward compatibility, i would suggest a nullcheck in the
> setBody for cases where the CamelContext is not set.
