Game stops when loading models. No error messages

When I load a model using:
[java]Spatial model = MainGame.getAsset().loadModel(name+".j3o");
System.out.println(“Mesh created”); [/java]
Then the game freeze.
The gui keeps working because the animations keep running. But the next line never prints.
It might be because I am missing to implement any of the jars into the build path? (im using eclipse)
If so, which jar is the one used for importing models?
Im using nightly build (2012-11-10)

Theres no way of getting any feedback from this method?
I meen, I have it printing every little detail I don’t need to know about, but when it comes to this method it prints nothing.
