Sonar violation: “Method may fail to close stream on exception”

Question

I have this method:

 private void unZipElementsTo(String inputZipFileName, String destPath) throws FileNotFoundException, IOException {

        OutputStream out         


        

Answer 1

That's right. The OutputStream.close() method can itself throw an exception. If this happens, e.g. on the 1st line of your finally{} block, then the other streams will be left open.
