Description:
There is a known issue when upgrading an existing administration domain (created with an earlier version of TIBCO Hawk) with TIBCO Hawk 4.8.0.


Symptoms
========
Once an existing domain client has been upgraded to TIBCO Hawk 4.8.0, its deployed applications enter an "unknown" state and can no longer be started. The tsm.log file will report java.lang.ClassCastException error messages.


Impact
======
The Hawk agent (of this domain client) cannot operate properly with the domain.


Workaround
==========
1. To remove the whole TIBCO Hawk 4.8 directory
2. To replace it with the TIBCO Hawk directory from 4.7
3. To restart the TRA Hawk agent.

For customers who are using TRA 5.x, it is recommended not to upgrade to Hawk 4.8.0 at the moment.


Resolution
==========
This issue will be fixed in an upcoming service pack release of TIBCO Hawk, expected Q3 2008. Please contact TIBCO Support for any additional question, including a better estimation of the release date.
