Description

Now Calcite no longer supports JDK 1.6 we can use AutoCloseable if we want to. It is more appropriate interface for releasing resources on close because it is not so tightly associated with I/O. (Closeable.close throws IOException.) Most, if not all, uses of Closeable in Calcite should instead use AutoCloseable.
