Hi,
nice, fast (single core) decompressor! I like it!

I tried to compress texts with your (new) compressor implementation. I took the source code from today. With some texts i get an java.lang.ArrayIndexOutOfBoundsException

I tried to break it down to the simples, shortest text which generates an error. There are even longer ones, which makes trouble.

I changed the main class of LBzip2OutputStream to:

public static void main( String[] args )
{
try
{
InputStream is = System.in;
OutputStream os = new LBzip2OutputStream( System.out, 900000, 10 );
os.write('c');
// os.write('e');
// byte[] buf = new byte[4096];
// int n;
// while ( ( n = is.read( buf ) ) > 0 )
// {
// os.write( buf, 0, n );
// }
// is.close();
os.close();
}
catch ( Throwable e )
{
e.printStackTrace();
}

this produce the following error:

java.lang.ArrayIndexOutOfBoundsException: -29
