3. It is possible to work around the first two issues by first creating a new Java project (Java Project -> Next -> Back), and then selecting Erlang Project -> Next. However:
* Naming the project and clicking "next" only causes the same NullPointerException as above to be thrown repeatedly
* Clicking "finish" causes a row of various exceptions:
