> Project: logback-core
> Issue Type: Bug
> Components: Joran
> Affects Versions: 0.9.17
> Reporter: tomliliu
> Assignee: Ceki Gulcu
> Priority: Blocker
> Fix For: 0.9.18

>
> User code opens an input stream from a jar file first. Then logback auto
> config loads the configuration file from the same jar. User code will get the
> following exception when read the input stream later.
> {code title="Stack Trace"}
> java.util.zip.ZipException: ZipFile closed
> at java.util.zip.ZipFile.ensureOpenOrZipException(ZipFile.java:413)
> at java.util.zip.ZipFile.access$1100(ZipFile.java:29)
> at java.util.zip.ZipFile$ZipFileInputStream.read(ZipFile.java:445)
> at java.io.FilterInputStream.read(FilterInputStream.java:116)
> at sun.nio.cs.StreamDecoder.readBytes(StreamDecoder.java:264)
> at sun.nio.cs.StreamDecoder.implRead(StreamDecoder.java:306)
> at sun.nio.cs.StreamDecoder.read(StreamDecoder.java:158)
> at java.io.InputStreamReader.read(InputStreamReader.java:167)
> at java.io.BufferedReader.fill(BufferedReader.java:136)
> at java.io.BufferedReader.readLine(BufferedReader.java:299)
> at java.io.BufferedReader.readLine(BufferedReader.java:362)
> {code}
> {code title="Reproduce"}
> InputStream resourceAsStream =
> Thread.currentThread().getContextClassLoader().getResourceAsStream(logLocation);
> BufferedReader reader = new BufferedReader(new
> InputStreamReader(resourceAsStream));
> final Logger logger = LoggerFactory.getLogger(LogbackBugReproduce.class);
> logger.debug(reader.readLine());
> {code}
> It looks like in
> ch.qos.logback.core.joran.GenericConfigurator.doConfigure(URL url) method:
> urlConnection.setDefaultUseCaches(false);
> InputStream in = urlConnection.getInputStream();
> doConfigure(in);
> in.close();
> The input stream is associated with the same zip file instance of the users.
> Then close the input stream will close the zip file that user currently is
> using.
> After changing it to:
> urlConnection.setUseCaches(false);
> InputStream in = urlConnection.getInputStream();
> doConfigure(in);
> in.close();
> The input stream is associated with a different zip file instance. Then close
> the input stream will not affect the zip file used by the user code.
