------------------------------
Resolution: Cannot Reproduce
> FileUtils.copyToFile backward incompatibility bug
> -------------------------------------------------
>
> Key: IO-609
> URL: https://issues.apache.org/jira/browse/IO-609
> Project: Commons IO
> Issue Type: Bug
> Affects Versions: 2.6
> Reporter: xia0c
> Priority: Major
>
> Hi,
> The following code snippets throw an IOException: Stream closed. It works
> well before commons-io 2.6. When I update commons-io to 2.6, it failed. There
> is a backward incompatibility bug behind it.
> The function code:
> {code:java}
> public class Demo {
> private void backupFile(String srcPath, String entryPath,
> ZipOutputStream stream) throws IOException {
> ZipEntry zipEntry = new ZipEntry(entryPath);
> stream.putNextEntry(zipEntry);
> Files.copy(Paths.get(srcPath), stream);
> }
> private void backupDir(String srcDir, String dstDir, ZipOutputStream
> stream) throws IOException {
> File dir = new File(srcDir);
> for (String path : dir.list()) {
> System.out.println(path);
> backupFile(dir.getAbsolutePath() + File.separator + path,
> dstDir + File.separator + path, stream);
> }
> }
> public void backup(String name) throws IOException {
>
> Files.createDirectories(Paths.get("/Users/chenlingchao/eclipse_projects/workspace/BBI.BugDetection"));
> ZipOutputStream stream = new ZipOutputStream(
>
> Files.newOutputStream(Paths.get("/Users/chenlingchao/eclipse_projects/workspace/BBI.BugDetection/tmp"
> + File.separator + name)));
> try {
>
> backupDir("/Users/chenlingchao/eclipse_projects/workspace/BBI.BugDetection/tmp",
> "meta" + File.separator + "tables", stream);
> stream.closeEntry();
> } finally {
> stream.close();
> }
> }
>
> public void restore(String name) throws IOException {
> ZipInputStream stream = new ZipInputStream(
>
> Files.newInputStream(Paths.get("/Users/chenlingchao/eclipse_projects/workspace/BBI.BugDetection/tmp"
> + File.separator + name)));
> try {
> ZipEntry entry;
> while ((entry = stream.getNextEntry()) != null) {
> FileUtils.copyToFile(stream, new
> File("/Users/chenlingchao/eclipse_projects/workspace/BBI.BugDetection/tmp" +
> File.separator + entry.getName()));
> }
> } finally {
> stream.close();
> }
> }
> }
> {code}
> The test code:
> {code:java}
> @Test
> public void TestDemo() throws IOException{
> Demo test = new Demo();
> test.backup("test.zip");
> test.restore("test.zip");
> }
>
> {code}
