Ok this error has nothing to do with GWT but with Errai. They iterate through the current working directory (CWD) to find the output folder to generate the server side marshalling classes. If the CWD has symbolic links this will apparently result in a NullPointerException. I have the strong feeling this is a bug (it should have a nullpointercheck).
