> Project: Commons Compress
> Issue Type: Bug
> Components: Compressors
> Affects Versions: 1.24.0
> Environment: Plain Java in IntelliJ
> Reporter: Ahmadin Badruddin
> Priority: Major
> Attachments: my10m.tar.bz2
>

> I tried to uncompress a big file (a few MBs) of bz2 file using
> BZip2CompressorInputStream, the max output I can get is 900000 in size.
> The following example
> {code:java}
> -rw-r--r-- 1 ahmadin staff 167283773 Nov 9 15:50 test.tar.bz2
> -rw-r--r-- 1 ahmadin staff 900000 Nov 9 15:51 test.tar {code}
> The code I use is the example from
> [https://commons.apache.org/proper/commons-compress/examples.html]
> {code:java}
> public class BZ2Extract {
> public static void main(String[] args) {
> int buffersize = 102400;
> InputStream fin = null;
> try {
> fin = Files.newInputStream(Paths.get("/cfm/test.tar.bz2"));
> BufferedInputStream in = new BufferedInputStream(fin);
> OutputStream out =
> Files.newOutputStream(Paths.get("/cfm/test.tar"));
> BZip2CompressorInputStream bzIn = new
> BZip2CompressorInputStream(in);
> final byte[] buffer = new byte[buffersize];
> int n = 0;
> while (-1 != (n = bzIn.read(buffer))) {
> out.write(buffer, 0, n);
> }
> out.close();
> bzIn.close();
> } catch (IOException e) {
> throw new RuntimeException(e);
> }
> }
> } {code}
> If I use bzip2 on my mac to uncompress, the file size is 1199749120 after
> uncompressing
