What Happened

17:09:09 [SEVERE] java.lang.NullPointerException: Cannot read the array length because "<local3>" is null

How It Happened

1. sub create as usual with the template that has 'world' folder in it
2. the exception is thrown
3. the server is created but the 'world' folder is empty

Any insight?

seems like a permission-related issue.
