[Chris Roberts (JIRA)]

    [ https://issues.jboss.org/browse/WFLY-2959?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12950375#comment-12950375 ] 

Chris Roberts commented on WFLY-2959:
-------------------------------------

I'll try and put a simple test app together, will take me a bit.
jackson-datatype-hibernate4:2.2.3 with hibernate 4.3.0 is a silent failure (it just fails to lazy initialise and triggers a lazy initialisation exception).
jackson:2.3.0/2.3.1 will exception whenever you include resteasy-jackson2-provider and exclude jettison/jackson1 in jboss-deployment-structure.xml and try and write with any simple JAXRS/JAXB resource with APPLICATION_JSON.

> Jackson was upgraded to 2.3.0 which contains a [bug|https://github.com/FasterXML/jackson-jaxrs-providers/commit/bafb6fb64bc15482c7bfc56784169204d6c4b1f2#commitcomment-5224156] that breaks RESTEasy. RESTEasy currently uses 2.2.1. Downgrading to at least 2.2.3, which is what CR1 is at, seems to resolve this issue.
> We should likely keep the version aligned with RESTEasy, but since CR1 was using 2.2.3 with no issues, I think reverting back to that should be fine.
