[jboss-jira] [JBoss JIRA] (ELY-1637) Change ReferralMode.toString to return value

[Philippe Marschall (JIRA)]

    [ https://issues.jboss.org/browse/ELY-1637?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13618135#comment-13618135 ] 

Philippe Marschall commented on ELY-1637:
-----------------------------------------

Old configurations stay valid because the parser calls `.toUpperCase()` on the value:

https://github.com/wildfly/wildfly-core/blob/master/elytron/src/main/java/org/wildfly/extension/elytron/DirContextDefinition.java#L194

New configurations with the new schema version with the enumeration will fail XML validation but should still get parsed. The serialization will produce valid XML in either case.

> The documentation of the referral-mode attribute in WildFly says the allowed values should be "ignore", "follow", "throw". However they are currently serialized as "IGNORE", "FOLLOW", "THROW". This is a WildFly issue and not an Elytron issue.
> However as part of the discussion on how to best fix WFCORE-3971 the easiest solution seems to be to change {{ReferralMode#toString()}}, that way the parser does not have to change.
> Once WildFly upgrades to a version of Elytron with this change a couple of tests will fail as the serialized model will intentionally change.
