[Migration operation] [Web to Undertow] migration of access-log prefix attribute doesn't take into account default value resulting in incosistent result. --------------------------------------------------------------------------------------------------------------------------------------------------------- Key: WFLY-5455 URL: https://issues.jboss.org/browse/WFLY-5455 Project: WildFly Issue Type: Bug Components: Web (Undertow) Affects Versions: 10.0.0.CR2 Reporter: Radim Hatlapatka Assignee: Stuart Douglas Priority: Optional Access log prefix in web subsystem is by default {{access-log.}}, in Undertow subsystem it is {{access-log}}. Note the difference, there is "." at the end in case of Web. There is inconsistency of migrate operation when migrating {{prefix}} attribute. When {{prefix}} is not explicitly defined in Web (=> default is used => {{access-log.}}, note the dot at the end. It is migrated to default Undertow prefix, which is {{access-log}} (missing "." at the end). In case of having explicitely set {{prefix="access-log."}}, it is the same value as the default value in Web and in this case this is migrated to {{access-log.}} (the "." is there). => two equivalent Web subsystem configuration of access-log result in two different configurations in Undertow, which is not expected behaviour. As this impacts only access-log naming, I am considering this only as minor issue.
