From JLS (14.8):

ExpressionStatement:
        StatementExpression ;

StatementExpression:
        Assignment
        PreIncrementExpression
        PreDecrementExpression
        PostIncrementExpression
        PostDecrementExpression
        MethodInvocation
        ClassInstanceCreationExpression

I would not put labeled block expression in the list of possible StatementExpressions.
So the only syntactically correct interpretation of the above example would be "a labeled block statement followed by an empty statement".

Am I missing something?
