[BATIK-736] NullPointerException when painting GraphicsNode onto Graphics2D impl with no associated DeviceConfiguration (i.e. SVGGraphics2D)

• Type: Bug

• Affects Version/s: 1.7
• Component/s: GVT

Description

When painting org.apache.batik.gvt.GraphicsNode uses utility class
org.apache.batik.ext.awt.image.GraphicsUtil. This utility fails to check for
null return values from Graphics2D.getDeviceConfiguration in at least two
places.

Steps two reproduce:
Create a GraphicsNode from a SVGDocument, paint onto SVGGraphics2D (or any
other Graphics2D impl whose getDeviceConfiguration returns null)
