O, that is good. In that case my analysis is either wrong or ecj has a
bug. The interaction between 1.5 covariant return types and 1.4 source
code is a little tricky. Maybe if you have time and have icedtea
installed then maybe you could also try compiling with the included
javac in that package. Then we might know which compiler is right.
