NullPointerException. Cannot invoke "org.apache.hc.client5.http.io.ManagedHttpClientConnection.isConsistent()" because "conn" is null about citrus

In case you know that this is fixed with httpclient version 5.3.1 you can explicitly add this version as a Maven dependency to your project (maybe in scope test). This should then use the newer version to run the tests.

We will also update the versions with the next Citrus release version then.

I will try to analyze the issue, but it can be challenging to grasp.

Why am I so sure that the problem has something to do with parallel startup? This error occurred for the first time when I ran the program in parallel, and it didn't happen if I disabled parallel execution. It's possible that it was just a coincidence, but it seems more likely that there's some underlying issue with parallel execution that needs to be addressed.

@christophd I'll try my best, but the error occurs in only 1 out of 50 instances, and it can be difficult to identify.
