Robbie Haertel commented on VFS-505:
------------------------------------
I'm still getting the original error. I'm not sure I noted the first time
around that it successfully reads a bunch of files before seemingly randomly
complaining that I'm reading from an output buffer.
> Reading from an input stream in a .tar ends up with a 'reading from an output
> buffer' exception

> Key: VFS-505
> URL: https://issues.apache.org/jira/browse/VFS-505
> Project: Commons VFS
> Issue Type: Bug
> Affects Versions: 2.0
> Reporter: Robbie Haertel
>
> This is probably the same issue as
> https://issues.apache.org/jira/browse/VFS-350, but for version 2.0 and for
> the .tar reader.
> The problem: After successfully reading some files from the .tar, I
> unexpectedly get:
> {noformat}
> Caused by: java.io.IOException: reading from an output buffer

> Note that I have several read-only streams open on the same .tar file. The
> are being read on the same thread, but reads to different files are
> interleaved. Even more interesting is that the same code path works fine when
> only reading a small subset of the data (this, too, includes interleaving
> reads to different files in the same .tar file). It may be a function of the
> number of bytes read.
> Note that I do NOT have any files open for writing.
