- Eclipse 3.5 says **yes**  
- Eclipse 3.6 says **no**  
- Intellij 9 says **yes**  
- Sun javac 1.6.0_20 says **yes**  
- GCJ 4.4.3 says **yes**    
- GWT compiler says **yes**    
- Crowd at my [previous Stackoverflow question][1] says **no**

My java theory understanding says **no**!

It would be interesting to know what [the JLS][2] is saying about it.
