Nullpointer when validating empty file
--
Key: PDFBOX-2173
URL: https://issues.apache.org/jira/browse/PDFBOX-2173
Project: PDFBox
Issue Type: Bug
Components: Preflight
Affects Versions: 1.8.6, 2.0.0
Reporter: Per-Olof Widström
Priority: Minor
Fix For: 1.8.8, 2.0.0
I am validating a PDF and I am getting a NullpointerException when the
filesize is 0 bytes. I looked at the code and saw a small misstake, and
therefore I am reporting this. I use version 1.8.6
{code:java|title=PreflightParser.java}
protected void checkPdfHeader()
{
//[snip]
String secondLine = reader.readLine();
byte[] secondLineAsBytes = secondLine.getBytes(encoding.name());
if (secondLine != null secondLineAsBytes.length = 5)
//[snip]
}
{code}
As you can see {{secondLineAsBytes}} is checked for null value, but only
after being called once.
{code}

h4. Workaround
Before validating, check the filesize, if it is larger than 0.
h4. How to reproduce
Try to validate with an empty file.
