Release Notes for 5.21.1
Summary
Bug fix
Unable to scan Xray attachments due to install sequence
Attachment Checker is using Xray’s services to retrieve Xray attachments for virus scanning.
If Xray is installed after Attachment Checker, will encounter NoClassDefFoundError.
If Xray is installed before Attachment Checker, but is later reinstalled or upgraded, will encounter “Service proxy has been destroyed” error.
This issue has been fixed and Attachment Checker should be able to scan Xray attachments regardless of the install sequence.
