Clean up RealmIdentity.exists() ------------------------------- Key: ELY-1221 URL: https://issues.jboss.org/browse/ELY-1221 Project: WildFly Elytron Issue Type: Task Components: API / SPI Reporter: Darran Lofthouse Assignee: Darran Lofthouse Priority: Blocker Fix For: 1.1.0.Beta50 The method requires some additional Javadoc to describe how it should be working. Additionally we should not use it to transition to the InvalidNameState, that state is specifically for when we can't map to a RealmIdentity.
