Tilman Hausherr commented on PDFBOX-3402:
-----------------------------------------
What JDK are you using? Can you open the file with PDFDebugger? I have no
trouble opening your file. Or could it be you have multiple libraries in your
classpath? Here's the code and the pom.xml I used:
{code}
package com.mycompany.mavenpdfboxproject;
import java.io.IOException;
import java.net.URL;
import org.apache.pdfbox.pdmodel.PDDocument;
public class Main
{
public static void main(String[] args) throws IOException
{
PDDocument doc = PDDocument.load(new
URL("https://issues.apache.org/jira/secure/attachment/12814018/EncryptedPDFWithEncryptedPassword.pdf";).openStream(),
"oMy/FeDNUygRh50N9SqDrCLWKYT5uCfx");
doc.close();
}
}
