I would guess that the reason is because Working Sets are somewhat 
orthogonal to Projects. They can cross project boundaries and can 
out-live Projects. Certainly a Working Set does not apply to just one 
Project, so they allow you to create a Java working set whose contents 
may include non-Java projects. Non-Java projects can contain .java files 
(as you've done), which might be included in a Java working set even if 
their project is not Java-aware.

HTH,
