BZip2CompressorInputStream throws IOException if underlying stream returns
available() == 0
-------------------------------------------------------------------------------------------
Key: COMPRESS-125
URL: https://issues.apache.org/jira/browse/COMPRESS-125
Project: Commons Compress
Issue Type: Bug
Components: Compressors
Affects Versions: 1.1
Reporter: Robert Lichtenberger
Priority: Minor
BzipCompressorInput,init() will throw an IOException, if the passed stream
returns 0 for available():
{code:title=BzipCompressorInput,.java|borderStyle=solid}
private void init() throws IOException {
...
if (in.available() == 0) {
throw new IOException("Empty InputStream");
}
...
}
{code}
I think this is not correct, because the underlying stream may indeed be able
to only return 0 bytes without blocking but may be able to block a little and
then return some more bytes.
Note also the change in the API documentation from: "Returns the number of
bytes that can be read " (1.4.2) to "Returns an estimate of the number of bytes
that can be read".
