Silence Tai commented on COMPRESS-492:
--------------------------------------
Maybe returning empty *Enumeration* is better?
> NullPointerException for 7zip files without file headers
> --------------------------------------------------------
>
> Key: COMPRESS-492
> URL: https://issues.apache.org/jira/browse/COMPRESS-492
> Project: Commons Compress
> Issue Type: Bug
> Components: Archivers
> Affects Versions: 1.18
> Reporter: Bernhard Geisberger
> Priority: Minor
> Labels: 7zip, nullpointerexception
> Attachments: sample.7z
>
>
> When loading a .7z file with correct headers and without files info headers
> using the SevenZFile class, a NullPointerException is thrown when calling
> getEntries or getNextEntry, because the archive.files member of SevenZFile is
> null. Ideally, a subclass of IOException should be thrown in this case.
> I attached an example file we encountered in our file processing pipeline,
> which causes the exception.
