I see the same exception with Camel 2.14.0
When I annotate a field I get the exception.
If I annotate a setter method the method is never called.
Did you ever find a solution?
In my case, the bean is a RouteBuilder extending SpringRouteBuilder

Re: @PropertyInject throws exception
Posted by Daniel Pocock <da...@pocock.pro>.
I created JIRA issues for this too
https://issues.apache.org/jira/browse/CAMEL-8125
- for the exception setting a field value
https://issues.apache.org/jira/browse/CAMEL-8126
- for the setter method on RouteBuilder not setting the value

Re: @PropertyInject throws exception
Posted by Claus Ibsen <cl...@gmail.com>.
Hi
How are you guys running Camel? standalone, WAR in Tomcat, OSGi or
something else?
And if you have a new stacktrace on Camel 2.14 or even 2.15-SNAPSHOT
then that is lovely as that's faster to find the code lines that has
the NPE
