Adding the relative-to property to transactions or messaging sub systems does not re-locate the files to the expected location.

Adding this entry to the transactions sub system
<object-store relative-to="tx-dir" path="tx-object-store"/>

and this property defined in the standalone.conf

-Djboss.server.path.tx-dir=/tmp

I would expect the files to be created here:

/tmp/tx-object-store

but they don't. Instead the system fails to start and shows this message.

New missing/unsatisfied dependencies:
service jboss.server.path.tx-dir (missing)

I have also tried running the server with this property. Instead of creating the files in /tmp they are created in a subdirectory of <as7-home>/standalone/data/tmp which ignores the definition of an absolute location on the file system.

-Dtx-dir=/tmp
