1. Create new project - ProjectY under some directory structure e.g. "com.cocom"
2. Invokde New -> Class on newly created project node ProjectY
3. Enter name "ClassX" and select packages under Filesystems:
com.cocom.ProjectY. Class can be created under project folder!
4. Press Finish button.

Class "ClassX" is created and its package statement is following "package
com.cocom.ProjectY" class itself is displayed twice in Workplace tab. Once as
normal Java object and second as shadow.

If we are using directory for projects storage then we have to preserve users
from creation of regular files under them. It is confusing.
