class "org.bouncycastle.asn1.ASN1Primitive"'s signer information does not match signer information of other classes in the same package

Question

I am trying to call the following line...

PdfCopy copy = null;
...
copy.setEncryption(password.getBytes(), null, PdfWriter.ALLOW_PRINTING | PdfWriter.ALLOW_COPY, PdfWriter.ENCRYPTION_AES_128)

I get

java.lang.SecurityException: class "org.bouncycastle.asn1.ASN1Primitive"'s signer information does not match signer information of other classes in the same package

This seems to be related to Grails and previous versions of bouncy castle so I tried adding the following to my pom...

But no dice.... I am using Grails 2.3.7 Anyone have any advice?

Also when I run mvn dependency:tree -Dverbose I don't see any other references.

Problem was related to the grails-doc plugin. I found this by running grails dependency-report this showed an old iText dependency in grails-doc.

Excluding this in the BuildConfig worked fine.

Basically this...
