Subject [jira] [Commented] (CAMEL-11615) WorkerPool is null for auto-configured RxJava-based application
Date Sun, 06 Aug 2017 07:31:00 GMT

    [ https://issues.apache.org/jira/browse/CAMEL-11615?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16115684#comment-16115684
] 

Claus Ibsen commented on CAMEL-11615:
-------------------------------------

Yeah I thought a bit on the same line to look at CamelSubscription so its subscribe method
would only start after camel context has been started. There is ways to hook into this. 

Take a look at
https://github.com/apache/camel/blob/master/camel-core/src/main/java/org/apache/camel/StartupListener.java

And then see how its used in other Camel components and see if you can find out how to hook
that into this component/subscriber.

> In https://github.com/qabbasi/reactive-camel-demo I'm using the camel-reactive-streams-starter
project to create a application based on RxJava2. Currently I'm getting a NPE during runtime.
> I also tried to test the sample route inside https://github.com/apache/camel/tree/master/examples/camel-example-reactive-streams,
but unfortunately this also results in the same exception:
> java.lang.NullPointerException: null
