I'm getting this runtime error after migrating to from 1.4.1 to 1.4.2:
```java.lang.IllegalStateException: Using blocking primitives on this dispatcher is not allowed. Consider using async channel instead or use blocking primitives in withContext(<http://Dispatchers.IO|Dispatchers.IO>) instead.```
It looks like it has something to do with Jackson. Is this a known issue?

The only thing I see in the changelog for 1.4.2 is this:
<https://youtrack.jetbrains.com/issue/KTOR-1186>

Found this issue:
