Wayne Chan updated PDFBOX-1412:
-------------------------------
Description:
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
