      Description

      For some test files on the Adobe Acrobat Engineering website, Preflight output looks like this:

      <preflight name="Disney-Flash.pdf">
      <executionTimeMS>210</executionTimeMS>
      <isValid type="">false</isValid>
      <errors count="3">
      <error count="1">
      <code>1.0</code>
      <details>Syntax error, Expected pattern 'obj but missed at character 'o'</details>
      </error>
      <error count="1">
      <code>1.2.1</code>
      <details>Body Syntax error, Expected pattern 'obj but missed at character 'o'</details>
      </error>
      <error count="1">
      <code>1.2.1</code>
      <details>Body Syntax error, Single space expected</details>
      </error>
      </errors>
      </preflight>

      Which suggests that Preflight doesn't correctly parse the objects. This is confirmed by a look at some of the offending PDFs in a hex editor, which reveals that the object identifiers in them are not terminated by any EOL character(s). AFAIK this is allowed in both PDF and PDF/A-1. More details + links to test files here ('Multimedia' table and below):
