[jira] [Reopened] (PDFBOX-1412) NullPointerException when getting
fields from a PDF file
[ https://issues.apache.org/jira/browse/PDFBOX-1412?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Wayne Chan reopened PDFBOX-1412:
--------------------------------
Still problem still exists in 1.8.2. The variable name has been changed but the issue still has not bee addressed. The problem is on line 540 of PDField.java. There needs to be a null check between line 539 and 540 to prevent a NPE. This is a critical bug that comes up when I try to parse most files with fields.

> I am getting a NullPointerException thrown from PDField.java line 540. The problem is that the code calls COSArray.getObject(i) on line 539, which can return a NULL. Line 540 uses the returned value without first checking for NULL, thus throwing NPE when the value is NULL. The following is the stack trace:
> java.lang.NullPointerException
