Martin Vogel from sirius-net GmbH informed me in an email about a possible problem with DAOS and Java agents.

If DAOS is activated on a database, in addition to the attachments from data documents, the jar files contained in a Java agent are also transferred to the DAOS repository if they exceed the set size.

I have been able to reproduce the problem with Domino V11.
I started with a freshly installed server, activated DAOS on the server

and enabled the database for DAOS.

load compact -c -DAOS ON barcode.nsf
[0B1C:0004-2C3C] 23.01.2020 18:26:48   Informational, DAOS has been enabled for database barcode.nsf.
[0B1C:0004-2C3C] 23.01.2020 18:26:48   Compacting barcode.nsf (barcode),  -c -DAOS ON barcode.nsf
[0B1C:0004-2C3C] 23.01.2020 18:26:48   Recovery Manager: Assigning new DBIID for C:\Domino\Data\barcode.nsf (need new backup for media recovery).
[0B1C:0004-2C3C] Clearing DBIID 5B9C3856 for DB C:\Domino\Data\barcode.ORIG
[0B1C:0004-2C3C] 23.01.2020 18:26:49   Compacted  barcode.nsf, 5K bytes recovered (<1%),  -c -DAOS ON barcode.nsf
[0B1C:0002-2F14] 23.01.2020 18:26:50   Database compactor process shutdown 

Result: Both archive files contained in the agent were transferred to the DAOS repository as NLO.

The agent continues to run without any issue.
