-------------------------------------
Summary: NPE error with invalid d that specifies only path end
Key: BATIK-1215
URL: https://issues.apache.org/jira/browse/BATIK-1215
Project: Batik
Issue Type: Bug
Affects Versions: 1.9, 1.7.1
Reporter: Ahmed Musallam
I am not very familiar with batik, but one of the products we use, does use
batik to read SVG files.
Browsers are typically forgiving with this issue, but seems like batik is
strict about it, in our SVG there is a path:
{{<path class="st1" d="z"/>}}
As you can see the d attribute only specifies path end, and understandably
batik throws the following error:
{quote}
the error can be produced by opening the offending SVG with
batik-squiggle-1.9.jar or batik-squiggle-1.7.jar
{quote}
{code:java}
java.lang.NullPointerException

I don't think batik should throw an NPE. Rather, the invalid d attribute should
be handled by either ignoring the path or throwing a different exception with a
helpful message.
Thank you for building this awesome library!
