Description

The following should throw IOException when given a truncated tar:

TarArchiveInputStream tarInput = new TarArchiveInputStream(inputStream);
TarArchiveEntry currentEntry;
while ((currentEntry = tarInput.getNextTarEntry()) != null) {
}

Instead, it completes successfully. I've included a small simple .tar, and a truncated version of it. Untaring from the command line fails properly:

$ tar -tf test_truncated.tar
test/
tar: Truncated tar archive
tar: Error exit delayed from previous errors.
