[jira] [Commented] (VFS-505) Reading from an input stream in a .tar ends up with a 'reading from an output buffer' exception

Bernd Eckenfels commented on VFS-505:
-------------------------------------

Do you still get it from 2.0 or also from 2.1?

>             Project: Commons VFS
>          Issue Type: Bug
>    Affects Versions: 2.0

> 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.
