[jira] Updated: (PDFBOX-710) XMPSchema.java:392 and XMPSchema.java:570 Possible null pointer dereference of bagElement

Posted by "Peter_Lenahan@ibi.com (JIRA)" <ji...@apache.org>.
     [ https://issues.apache.org/jira/browse/PDFBOX-710?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Peter_Lenahan@ibi.com updated PDFBOX-710:
-----------------------------------------

    Attachment: XMPSchema-Findbugs-possible-null-pointer-reference.txt
                XMPSchema.java

This patch simply checks for null before referencing the objects.

I have no reproduction for the problem, just a bug that Findbugs reported, and it was easy to fix.

Thanks,
Peter
