We have an application that creates PDFs unsing jasperreports.  

It also manipulates said PDFs using iText after they have been created.

We recently started using encryption on some PDF. That means before the app can handle the PDF after its creation, it has to be decrypted. While attempting to do so using iText's `PdfReader(String path, byte[] password)` I get the following exception:

```

```

The project is built as a runnable .jar using Maven and uses the following dependencies:  

iText 5.4.2  

bouncycastle 1.48

I should mention that jasperreports has its own dependency of iText and bouncycastle:  

iText 2.1.7  

bouncycastle 1.38

I can't figure out what's going on on and need help.
