2.0.3
You're right, a warning is probably OK too. However it is still an incorrect
PDF.

> On Friday our production log system alerted us that we had an error ("dash
> lengths all zero, ignored"). We investigated and found that the PDF processed
> gave an error when opening it up in Adobe Reader as well but the page looked
> fine and was processed fine as well. But still we got this error. For us this
> is a false positive, even though a line pattern should not be empty the page
> isn't broken or can't be viewed so why handle it as an error.
> My suggestion is to handle the errors in the code below as an information
> logging or warning.
> In our case we got an update 1 hour later with a PDF that didn't have the
> empty line dash pattern.
> {code:title=SetLineDashPattern.java|borderStyle=solid}
> for (COSBase base : dashArray)
> {
> if (base instanceof COSNumber)
> {
> COSNumber num = (COSNumber) base;
> if (num.floatValue() != 0)
> {
> allZero = false;
> break;
> }
> }
> else
> {
> LOG.error("dash array has non number element " + base + ",
> ignored");
> dashArray = new COSArray();
> break;
> }
> }
> if (dashArray.size() > 0 && allZero)
> {
> LOG.error("dash lengths all zero, ignored");
> dashArray = new COSArray();
> }
> {code}
