Stefan Bodewig resolved COMPRESS-348.
-------------------------------------
Resolution: Fixed
Fix Version/s: 1.12
> Calling SevenZFile.read() on empty SevenZArchiveEntry throws
> IllegalStateException
> ----------------------------------------------------------------------------------
>
> Key: COMPRESS-348
> URL: https://issues.apache.org/jira/browse/COMPRESS-348
> Project: Commons Compress
> Issue Type: Bug
> Affects Versions: 1.11
> Reporter: Robin Jansohn
> Priority: Minor
> Fix For: 1.12
>
>
> I'm pretty sure COMPRESS-340 breaks reading empty archive entries. When
> calling getNextEntry() and that entry has no content, the code jumps into the
> first block at line 830 (SevenZFile.class), clearing the
> deferredBlockStreams. When calling entry.read(...) afterwards an
> IllegalStateException ("No current 7z entry (call getNextEntry() first).") is
> thrown. IMHO, there should be another check for entry.getSize() == 0.
> This worked correctly up until 1.10.
