Comment 1 Olivier Thomann CLA 2002-03-08 12:46:46 EST 
In general this means it is a missing case. Should be fixed quickly.
Comment 2 Olivier Thomann CLA 2002-03-08 13:03:43 EST 
I don't know why I was rejecting the case where a local declaration was a 
statement. This is naturally possible. In this example, List l = null; should 
be converted to a VariableDeclarationStatement.
Fixed and released in HEAD.
