Subject [jira] [Commented] (COMPRESS-418) ZipArchiveEntry duplicates the size field from ZipEntry
Date Mon, 24 Jul 2017 12:27:00 GMT

    [ https://issues.apache.org/jira/browse/COMPRESS-418?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16098289#comment-16098289

Darryl L. Pierce commented on COMPRESS-418:
-------------------------------------------

Yes, using ZipFile instead of ZipArchiveinputStream works as expected.

Though I do think it's still a bug that ZAIS does not work as desired; i.e., using the Java
debugger I do see the two instance variables and, though one holds the entry's size, the getSize()
method always returns -1 on archives created by the Compress libraries.

>                 URL: https://issues.apache.org/jira/browse/COMPRESS-418
>             Project: Commons Compress
>          Issue Type: Bug
>          Components: Archivers
>    Affects Versions: 1.14
>         Environment: Java 1.8.0_131
> Apache Compress 1.14
>            Reporter: Darryl L. Pierce
>            Priority: Critical
>
> I create an archive using Apache Compress. I can read the archive fine using 7zip and
JAR (from the JDK).
> When I read the same archive using Apache Compress libraries, I get a NegativeArraySizeException
on every entry.
> When I read any other archive using Apache Compress libraries, I do not get the NegativeArraySizeException
on entries.
> When I debug this, I see that the ZipArchiveEntry object has two instance variables named
size (one it defines, which contains the correct size, and one it inherits from ZipEntry which
is -1). And it seems that, on Apache Compress-created archives, it's always returning the
inherited value and not the one defined by ZipArchiveEntry.
> In my code, I am only use instances of ZipArchiveEntry.
