[ https://issues.jboss.org/browse/WFLY-11166?page=com.atlassian.jira.plugin... ] David Lloyd commented on WFLY-11166: ------------------------------------ Even this one subtask might be a bit more complex than it appears. The three types mentioned in the summary are _always_ available, thanks to the transaction client library. The real capability from the perspective of the usage of these three types is the local transaction provider, which would normally come from the org.jboss.as.transaction extension. And yet, if no subsystem provides the capability, the system may still be usable. The transaction client library will still function, though certain transaction-related operations will obviously be disallowed. Additionally, it's not impossible that at some point in the future we may support more than one local transaction provider at once, with an application- or component-specific manner of selecting the provider to use. -- This message was sent by Atlassian Jira (v7.12.1#712002)
