Description

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:
