> I posted this on the mailing list but got no answer. I'm describing here some
> behaviors that are triggering NPE when saving a modified pdf document.
> What I'm trying to do is to open an encrypted document, modify it, save it
> back (I attached my test project). The three tests I made they all end up
> with a NPE but they work if I turn on setAllSecurityToBeRemoved (and I don't
> want security to be removed).
> First test:
> 1- input is a doc encrypted with owner pwd having the modify permission on.
> 2- The document is loaded and decrypted using owner pwd.
> 3- permissions.isOwnerPermission() is true which is correct
> 4- permissions.canModify() is true which is correct
> 5- modify the doc and save throws a NPE which is NOT correct
> Second test
> 1- input is a doc encrypted with owner pwd having the modify permission on.
> 2- The document is loaded but not decrypted
> 3- permissions.isOwnerPermission() is true, why? I didn't provide any owner
> pwd I should not have owner permissions.
> 4- permissions.canModify() is true which is correct
> 5- modify the doc and save throws a NPE which is NOT correct
> Third test
> 1- input is a doc encrypted with owner pwd having NO permission.
> 2- The document is loaded and decrypted using owner pwd.
> 3- permissions.isOwnerPermission() is true which is correct
> 4- permissions.canModify() is true, why? I can modify the doc because I have
> owner permission but the Modify should be off.
> 5- modify the doc and save throws a NPE which is NOT correct
