Description

Using the cli I encounter an NPE whenever I use the `validate` option. I'm assuming no one but this gnarly old fogey ever tries

 

```minimal.svg

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">
<svg width="100" height="100" xmlns="http://www.w3.org/2000/svg">
    <rect fill="#ff0000" x="0" y="0" width="50" height="50"/>
</svg>

```

 

```shell

java -jar ~/bin/batik-1.14/batik-rasterizer-1.14.jar -validate minimal.svg

```

 

```stacktrace
