[jira] [Comment Edited] (PDFBOX-3595) For a PDF - Loading from URL
works. Loading from BAIS does not.

String contents = IOUtils.toString(new URL(url).openStream());

You're converting binary data to a java string and back. Why are you expecting that this would work?

> Key: PDFBOX-3595
> URL: https://issues.apache.org/jira/browse/PDFBOX-3595
> Project: PDFBox
> Issue Type: Bug
> Components: Parsing
> Affects Versions: 1.8.12, 2.0.3
> Environment: Windows
> Reporter: David Medinets
> Priority: Minor
>
> I've found several PDF files at https://www.supremecourt.gov/opinions/boundvolumes.aspx that throw an exception when using PDDocument.load with a ByteArrayInputStream but do not throw an exception when the same PDF is loaded using a URL.
> v1.8.12 is the last version in which the load method takes a URL object. I mention it here in case that reference point of 'working' code helps diagnose this issue.
>
> Below is the complete program that shows the two approaches. The first works. The second does not.
> ```
> package com.affy.wildtuna.adrivers;
> import java.io.ByteArrayInputStream;
> import java.net.URL;
> import org.apache.commons.io.IOUtils;
> import org.apache.pdfbox.pdmodel.PDDocument;
> public class ShowInvalidDistancesSetException {
> public static void main(final String[] args) throws Exception {
> String url = "https://www.supremecourt.gov/opinions/boundvolumes/545bv.pdf";
> PDDocument doc01 = PDDocument.load(new URL(url));
> doc01.close();
> System.out.println("Loading from URL works.");
>
> String contents = IOUtils.toString(new URL(url).openStream());
> try (ByteArrayInputStream bais = new ByteArrayInputStream(contents.getBytes())) {
> PDDocument doc = PDDocument.load(bais);
> doc.close();
> }
> }
> }
> ```
> Here is the program's output:
> ```
> WARNING: Specified stream length 6845 is wrong. Fall back to reading stream until 'endstream'.
> Loading from URL works.
