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

             Summary: Invalid ZIP throws different exception in 1.21
                 Key: COMPRESS-622
                 URL: https://issues.apache.org/jira/browse/COMPRESS-622
             Project: Commons Compress
          Issue Type: Bug
          Components: Archivers
    Affects Versions: 1.21
            Reporter: Nirmal Vettiankal
         Attachments: zbsm.tmp

I have an invalid zip file (attached) that is throwing a ZipException in 1.20 and an IOException in 1.21.

 

With the following code:
{code:java}
import java.nio.file.Paths;
import org.apache.commons.compress.archivers.zip.ZipFile;

public class ApacheCompressTest {

    public static void main(String... args) {
        try {
            new ZipFile(Paths.get("src/main/resources/zbsm.tmp").toFile());
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

} {code}
 

Output in 1.20:
{code:java}

    at ApacheCompressTest.main(ApacheCompressTest.java:8)
{code}
