Till Kolditz closed PDFBOX-4195.
--------------------------------
Resolution: Fixed
This is a problem when invoking the runnable jar file with Java 9, because the
modules "java.activation" and "java.xml.bind" are not included in the classpath
by default, any longer. The following command line argument solves the issue:
{{--add-modules java.se.ee}}

> Key: PDFBOX-4195
> URL: https://issues.apache.org/jira/browse/PDFBOX-4195
> Project: PDFBox
> Issue Type: Bug
> Components: Preflight, XmpBox
> Affects Versions: 2.0.8, 2.0.9
> Environment: Windows, Java 9.0.4, MikTeX 2.9, pdflatex processor
> Reporter: Till Kolditz
> Priority: Minor
> Labels: patch
>
> I came across this issue when I compiled a PDF file with miktex LaTeX
> processor, using the pdfx package with options [a-1b,pdf17] and then
> validating the generated PDF file using the preflight stand-alone jar files
> "preflight-app-2.0.8.jar" and "preflight-app-2.0.9.jar". Java version is
> 9.0.4. The error message is:
> {{7.1 : Error on MetaData, Failed to instanciate DateType property with value
> 2018-04-17T22:24:06+02:00 in xmp:ModifyDate}}
> However, according to the XMP specification Section 8.2.1.2 at
> [https://wwwimages2.adobe.com/content/dam/acom/en/devnet/xmp/pdfs/XMP%20SDK%20Release%20cc-2016-08/XMPSpecificationPart1.pdf]
> this date format should be valid. A given example date is:
> {{2004-10-23T12:00:00-06:00}}
> The problematic class should be DateConverter, which seems to not handle time
> zone information properly:
> [https://javalibs.com/artifact/org.apache.pdfbox/xmpbox?className=org.apache.xmpbox.DateConverter&source]
> in function
> {{public static Calendar toCalendar(String date) throws IOException}}
> I adapted the source code to print a full stack trace:
> {{7.1 : Error on MetaData, Failed to instanciate DateType property with value
> 2018-04-18T09:37:03+02:00. Error type: InvocationTargetException. Error
> message: null. StackTrace: java.lang.reflect.InvocationTargetException}}
