Splunk Add-on for Java Management Extensions: Why is the host field not being extracted?

The TA for JMX doesn't seem to be extracting the host field, so all my events appear to come from the heavy forwarder running the add-on. The stanza in transforms is attempting to match on a string starting with host= but I don't see that in any of the data being collected. Here's the stanza included with the app:

 [extract-host]
 DEST_KEY = MetaData:Host
 REGEX = host=([a-zA-Z0-9\._-]+)
 FORMAT = host::$1

hi, we're setting host to "the instance of the Splunk forwarder that collected the data" and setting source to "the instance of the Java Management Extensions that produced the data", because we may have a 1:many relationship of forwarders and JMX sources.

Thanks. FWIW, this was ultimately rendered moot by running the TA on each UF, connecting to localhost go get the data.
