The JAX-RS JSON configuration does not work with JBoss EAP 7 anymore

Solution Unverified - Updated -


  • In JBoss EAP 6, we plugged our own ObjectMapper to configure JSON fields when using the RESTEasy Jackson provider. In EAP 7, it seems that this configuration is ignored.
  • We configured the JSON Date format for the Jackson provider by following the suggestion in this knowledge article and it worked fine in EAP 6. However, the same application does not work anymore in EAP 7. What is wrong?
