Description of problem:
In log subsystem, nested expression can be used for path.
~~
"path" => {
                        "type" => STRING,
                        "description" => "The filesystem path.",
                        "expressions-allowed" => true,
                        "nillable" => false,
                        "min-length" => 1L,
                        "max-length" => 2147483647L
                    }
~~

so if I use following log configuration :
~~~
<periodic-rotating-file-handler name="FILE" autoflush="true">
                <formatter>
                    <named-formatter name="PATTERN"/>
                </formatter>
				<file relative-to="jboss.server.log.dir" path="${jboss.server.name}.log"/>
                <suffix value=".yyyy-MM-dd"/>
                <append value="true"/>
~~~

server log name will be HOST_NAME.log and there is no problems to write.

However, it is not displated in Admin console Log Viewer menu.

Version-Release number of selected component (if applicable):
6.4.beta

How reproducible:
change path in <periodic-rotating-file-handler> file element to ${jboss.server.name}.log

Then see admin console menu.
Steps to Reproduce:
1.

Actual results:
empty

Expected results:
~.log file should be shown.
