I am, as I have said before, taking a working application that used PDFBox
1.8.9 amd updating it for 2.0.
I have fixed everything (with the help of the excellent people on this
list) but one bug persists.
I have visual signature code which is an adaptation of the Visible
Signature example included in the PDFBox examples.
Before it just worked (though there were some issues).
But when I went to 2.0 I began to get the infamous 'JCE cannot authenticate
the provider BC' exception.
*java.io.IOException: error constructing MAC: java.lang.SecurityException:
JCE cannot authenticate the provider BC at

The code that causes this is just
* Provider provider = new BouncyCastleProvider();*
* KeyStore keystore = KeyStore.getInstance("PKCS12", provider);*
* char[] pin = pinString.toCharArray();*
* keystore.load(ksInputStream, pin);*
(presume with me that the pin and the input stream are OK.)
There have been absolutely no code changes whatsoever in the code path in
question and the only change to the build (I am building with maven) is to
replace 1.8.9 with 2.0.
It is a long shot but maybe this is a FAQ, or maybe someone will say 'of
course, because we changed this in 2.0!'
Or maybe not.
But if anyone has an idea please clue me in. Stack overflow has a variety
of answers but they all relate to things that have nothing to do with what
I am soing, or do not explain why it used to work pre-2.0 and doesn't with
2.0.
Thank you.
