I did read it then for some reason did nothing.
The problem is that the return value is an array backed by the
annotation COSArray, so this doesn't really work if we'd have a
different number in the COSArray and in the annotation array.
However I see that it is already done that we skip stuff if it is
filtered, so maybe we should skip exceptions as well. It looks
like this
now:
PDAnnotation createdAnnotation =
PDAnnotation.createAnnotation(item);
if (annotationFilter.accept(createdAnnotation))
{
actuals.add(createdAnnotation);
}
and we could change it like this:
try
{
PDAnnotation createdAnnotation =
PDAnnotation.createAnnotation(item);
if (annotationFilter.accept(createdAnnotation))
{
actuals.add(createdAnnotation);
}
}
catch (IOException ex)
{
LOG.error(ex.getMessage(), ex);
}
Can you share such a file?
