It probably isn't finding the JPEG writer. So this line:
ImageWriter writer = ImageWriterRegistry.getInstance()
.getWriterFor("image/jpeg");
Is returning NULL. This is typically caused by Batik not
being able to find the file:
resources/META-INF/services/org.apache.batik.ext.awt.image.spi.ImageWriter
Or potentially an inability to create the JPEGImageWriter
(possibly due to a lack of the com.sun.image.codec.jpeg classes.
