Extraction of text from secured PDFs throws runtime exception
Hi
I recently noticed the following runtime exception in my application when trying to extract text from secured PDFs:
java.lang.VerifyError: (class: org/bouncycastle/cms/CMSSignedDataParser, method: replaceSigners signature: (Ljava/io/InputStream;Lorg/bouncycastle/cms/SignerInformationStore;Ljava/io/OutputStream;)Ljava/io/OutputStream;) Incompatible argument to function
I am using PDFBox 1.8.6 and I use these APIs:
document = PDDocument.load(is, true);
if (document.isEncrypted()) {
PdfUtil.decryptPDFDoc(document);
}
...
I am assuming the error is occurring in the decryptPDFDoc() call?
My maven pom dependencies are:
<dependency>
<groupId>org.bouncycastle</groupId>
<artifactId>bcprov-jdk15</artifactId>
<version>1.44</version>
</dependency>
<dependency>
<groupId>org.bouncycastle</groupId>
<artifactId>bcmail-jdk15</artifactId>
<version>1.44</version>
</dependency>
Have I got this right?
Thanks for any pointers.
- Chris

Hi,
you can find the pom.xml used for the 1.8.6 release at http://svn.apache.org/viewvc/pdfbox/tags/1.8.6/pdfbox/pom.xml?view=markup to verify your settings.

Hi,
always use the latest version of PDFBox, which is 1.8.8.
I don't know what happens in "PdfUtil.decryptPDFDoc". The correct call
is openProtection().
