JsonNode missing in Index
**Describe the bug**
I get a log output about missing `com.fasterxml.jackson.databind.JsonNode` in the jandex index.
That class comes from jackson.

**Expected behavior**
No warn log output about missing classes in the index.

**Actual behavior**
I get the following output:
```
03.03.2020 09:02:22 WARN  [io.quarkus.deployment.steps.ReflectiveHierarchyStep] Unable to properly register the hierarchy of the following classes for reflection as they are not in the Jandex index:
        - com.fasterxml.jackson.databind.JsonNode
Consider adding them to the index either by creating a Jandex index for your dependency via the Maven plugin, an empty META-INF/beans.xml or quarkus.index-dependency properties.");.
```


**To Reproduce**
Have JsonNode as part of a request body.
