------------------------------------
Gary,
I'm encountering problems with the HEAD of trunk. In the interest of full
disclosure, I've never used Maven before. When I run mvn install, several of
the tests fail. So I I'm forced to use mvn -Dmaven.test.skip=true install
instead. I copy the commons-vfs2-2.1-SNAPSHOT.jar from the Maven repository to
my Eclipse project and update the build path (remove the old .jar, add this new
one). Now I get a different exception; it doesn't seem to be recognizing the
.tar loader:
Exception in thread "main" org.apache.commons.vfs2.FileSystemException: Badly

> 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.
