[classlib][archive] unexpected IOException for double ZipInputStream().close()

                 Key: HARMONY-1101
                 URL: http://issues.apache.org/jira/browse/HARMONY-1101
             Project: Harmony
          Issue Type: Bug
          Components: Classlib
            Reporter: Vladimir Ivanov

The spec says for the method java.io.Closeable.close(): "If the stream is already closed then
invoking this method has no effect".
The spec for java.util.zip.ZipInputStream.close() says nothing for double call but RI follow
the spec for Closeable and do nothing while Harmony throws IOException.

            BufferedInputStream b = new BufferedInputStream(new FileInputStream(f)); 
            zis = new ZipInputStream(new BufferedInputStream(b)); 
        } catch (IOException e) { 
            System.out.println("unexpected exception: " + e);
