3. Upload a PDF that is encrypted/password locked. Note the EncryptedDocumentExceptions that are generated.
4. Return to Documents & Media. Note that your PDF has been successfully uploaded.
5. Select the PDF you have just uploaded. The UI should state that no preview could be generated.

Actual: Exceptions are thrown. See below:

Reproduced in:

Master

7.2.x

7.1.x

7.0.x - behavior is currently different than in all other branches due to the fact that LPS-86455 has not been backported yet. This fix will still be needed once it's backported, however.
