Note that on line #42 of LutViewer.run() apparently the call to createImage() returned null. This call is a Java method of Component (the ImageJ class extends Frame). The documentation of that method says:
"Returns: an off-screen drawable image, which can be used for double buffering. The return value may be null if the component is not displayable. This will always happen if GraphicsEnvironment.isHeadless() returns true."
