-----------------------------------------

             Summary: Inconsistency with latest PKZip standard
                 Key: COMPRESS-549
                 URL: https://issues.apache.org/jira/browse/COMPRESS-549
             Project: Commons Compress
          Issue Type: Bug
    Affects Versions: 1.20
            Reporter: Sebastian Kürten


I came across some Zip archives that cannot be read using 
ZipArchiveInputStream. Investigating the issue, I found that 
java.util.zip.ZipInputStream from the JDK shows the same behavior while 
java.util.zip.ZipFile seems to do fine. For java.util.zip.ZipInputStream, the 
issue has been reported here: 
[https://bugs.openjdk.java.net/browse/JDK-8143613] and an example file is 
provided. I copied the testing file into a repository for testing. Here's the 
example file: 
[https://github.com/sebkur/test-zip-impls/blob/master/src/test/java/de/topobyte/zip/tests/jdk8143613/TestData.java]
 and the test that fails reading that data using ZipArchiveInputStream: 
[https://github.com/sebkur/test-zip-impls/blob/master/src/test/java/de/topobyte/zip/tests/jdk8143613/TestCommonsZipInputStream.java]
 

 

If this file is indeed a ZIP archive consistent with the PKZip spec, I think 
commons-compress does not work according to the spec. I would appreciate if 
someone could look into this and verify if this is indeed a bug in 
commons-compress. Thanks!
