      Description

        While general expression support was outlawed for the try-with-resources statement during the developement of Java SE 7, it would be helpful to allow limited expression support in the form of final or effectively final variables. Using (effectively) final variables avoids the need to declare a dummy variable for the purpose of using the try-with-resources statement and avoid the semantic ambiguity of whether the close method should be called on the initial or final value of the variable.
