Content download fails with error “ MethodRequestHandler Exception: An exception occured while processing the request” for content recently uploaded to a file server in Windchill 10.2 M010

• When attempting to download content, the download fails with error “ MethodRequestHandler Exception: An exception occured while processing the request”.
• The content was originally uploaded to a cache vault on a remote file server.
• Windchill is configured for ad-hoc replication through the property setting wt.fv.master.adhocCaching=1 in <Windchill>/codebase/wt.properties.
• The content is covered by an existing replication rule for the file server.
• Steps to reproduce:

1. Ensure that wt.fv.master.adhocCaching.flag=1 is set in <Windchill>\codebase\wt.properties on the master.
2. Set the preference Vaulting and Replication > Preferred File Server to the file server.
3. Create a new document with content; the content is uploaded to the file server cache vault.
4. Change the preference Vaulting and Replication > Preferred File Server to the master server.
5. Attempt to download the content of the newly created document.

• The following stack trace is thrown in the master Method Server log:
