> Current master fails to extract ActiveMQ tar archive
> ----------------------------------------------------
>
> Key: COMPRESS-558
> URL: https://issues.apache.org/jira/browse/COMPRESS-558
> Project: Commons Compress
> Issue Type: Bug
> Affects Versions: 1.21
> Reporter: Robin Schimpf
> Priority: Major
> Time Spent: 10m
> Remaining Estimate: 0h
>
> While version 1.20 is able to extract the ActiveMQ tar archive which can be
> found here ([https://activemq.apache.org/components/classic/download/]) the
> current master fails at extracting it with the following exception
> {code:java}
> java.io.IOException: Error detected parsing the header
> at
> org.apache.commons.compress.archivers.tar.TarArchiveInputStream.getNextTarEntry(TarArchiveInputStream.java:385)
> {code}
> I made a bisect search and this reveals the error is introduced with
> COMPRESS-509. I made an analysis and found the following why the problem
> appears
> * Error ist thrown after reading a file in the tar but the file has a "/" at
> the end
> * In the currEntry.isGNULongNameEntry the currEntry.isDirectory evaluates to
> true for this file -> reason why the "/" is appended
> * The underlying problem is that isDirectory also checks if the entry has a
> "/" at the end. But the decoded file name is not yet set in the currEntry.
> Since the entry before the file is a folder the name ends with "/" and
> isDirectory returns the wrong value
> Since I already came this far I'll send a pulll request where the decoded
> name is set before checking if we need to append "/" to the entry name. With
> this change the ActiveMQ tar can be extracted correctly again.
