What steps will reproduce the problem?

1. RayHandler rayHandler = new RayHandler(world);

What is the expected output? What do you see instead?

Expected output is a RayHandler.
I get an exception instead: 

Exception in thread "LWJGL Application" java.lang.IllegalArgumentException: no 
position attribute was specified

OP here. I managed to resolve my issue by downloading nightlies from LibGDX, 
and also building Box2DLights from source. It now works perfectly again. :-)

Same problem here. According to the debugging I did the problem comes from the 
Usage class inside the class VertexAttributes in the package 
com.badlogic.gdx.graphics. The constant values were changed and therefore 
Box2dLights could not find the position attribute (and other attributes) in the 
attributes array. Building Box2DLights from source with the  same libgdx 
version you use in your game (the latest nightly in this case) should fix the 
problem.

Thanks for the 'build from source' suggestion, I will keep the source checked 
out in eclipse for future use.

Some thing. Only i've got a different exception:

Exception in thread "LWJGL Application"

Version box2dlights from 29 may. Error in a same place:
RayHandler rayHandler = new RayHandler(world);

This is a duplicate to issue #18.
As stated the issue occurs when box2dlights is not run with latest nightlies 
from libGdx. The current nightly version of the Usage enum differs from the one 
in the latest release.
