Lazy sequences do not interact well with resources that need to be closed. This is a long-standing issue, and no universal solution has been found.
The usual recommendation is to manage the resource in a higher scope than the process that uses it. In your case, rather than creating the iterator and seq in the same function, create the iterator higher up the call stack where it can be managed by 'with-open' or an equivalent. Then create the lazy seq where you need it. As to why iterator-seq doesn't work, your code appears to be using an Iterator interface (peekNext) which is different from Java's standard iterator: http://docs.oracle.com/javase/6/docs/api/java/util/Iterator.html -S -- You received this message because you are subscribed to the Google Groups "Clojure" group.
