[Eduardo Martins (Jira)]

    [ https://issues.jboss.org/browse/WFLY-12384?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13771958#comment-13771958 ] 

Eduardo Martins commented on WFLY-12384:
----------------------------------------

Right, I will need to discuss internally how we will  deprecate/remove such
config attribute, but there is no alternative to that so guess customer can
proceed to fix it on their side in advance.
