Description
To reproduce this, simply launch gov.nasa.worldwindx.examples.SurfaceImag eViewer and try to add a DTED file. Here is the exception:
Exception in thread "Thread-23" java.lang.NullPointerException

A new AVList argument was added to gov.nasa.worldwind.formats.dted.DTED.rea d()
This gets called by gov.nasa.worldwind.data.DTEDRasterReader .doRead(), which has always accepted an AVList argument, but now it passes it to the read() method.
The problem happens in the line in bold. We still send a null value for the AVList argument, but this null eventually gets operated on, leading to the NPE.
