Symptoms

When using any of the file attachment PeopleCode functions (i.e. AddAttachment, ViewAttachment, DetachAttachment, GetAttachment, PutAttachment, DeleteAttachment, etc.), and URL Definition used is a SFTP server with public key authentication, the user is kicked out of the application.  The trace stops abrutly without any error, and similarly there were no telling errors in the Application Server logs.  If used in an Application Engine program, the Application Engine program stops without additional errors.

The problem was found to be specific to SFTP servers only, and only when public key authentication was used.  Password authentication works fine.

SAMPLE STEPS
---------------
The issue can be reproduced with the following steps:
1. PeopleTools > Utilities > Debug > PeopleTools Test Utilities
2. For URL Id or String URL textbox, enter the URL Definition for the SFTP server, e.g. URL.SFTP_SERVER_TEST
3. Use "Add" button to upload a test file
4. Select a file
5. Click upload
6. User is kicked out of the system
