Connector attribute max-save-post-size is neither migrated nor migration writing is shown

Try calling :migrate operation on Web subsystem with connector defined like this: <connector name= "http" protocol= "HTTP/1.1" scheme= "http" socket-binding= "http" max-connections= "100" max-post-size= "2048000" enable-lookups= "true" max-save-post-size= "4092" /> And see that there is no migration warning even though the attribute wasn't migrated (see created http listener in undertow subsystem: <http-listener name= "http" max-connections= "100" max-post-size= "2048000" resolve-peer-address= "true" socket-binding= "http" />
