[jboss-jira] [JBoss JIRA] (WFLY-5541) Webservice subsystem abuses attribute values for error handling

[Brian Stansberry (JIRA)]

    [ https://issues.jboss.org/browse/WFLY-5541?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13119489#comment-13119489 ] 

Brian Stansberry commented on WFLY-5541:
----------------------------------------

Points V. and VI. in that description are the most directly relevant one to situations where statistics are disabled.

If fixing this will result in changes to the management API (e.g. by declaring that metrics may now return undefined whereas before they wouldn't because an exception would be thrown) then it's quite important to get this fixed in WF 10 so we aren't forced to make API changes later.
