Syslog drains no longer update application name changes without a restart

I am a Platform Architect submitting this for a customer.

Issue

Syslog org.space.appname tag is not updated when an application name is changed via a syslog drain.

Context

Previous to PAS 2.8, an application could be renamed and the "org.space.appname" tag in syslog messages sent through a syslog drain would be dynamically updated. As of PAS 2.8, presumably because of a change in syslog adapter, these tags are no longer updated when an application name is changed unless the application is restarted/restaged.

Steps to Reproduce

Deploy an application
Bind to a syslog drain
Observe the syslog events
Rename the application
Observe the syslog events

Expected result

The org.space.appname tag would change on new syslog events after the application name is changed.

Current result

The "appname" tag remains the old application name after the application name is changed.

Start with the syslog adapter and trace how application name changes reach new syslog drain events. Reproduce the deploy, bind, rename, and event-observation sequence described in the issue, then verify that subsequent events use the new org.space.appname value without restarting or restaging.
