> The bug is in luni/src/main/native/luni/unix/OSFileSystemLinux32.c, method Java_org_apache_harmony_luni_platform_OSFileSystem_transferImpl.
> Parameter Offset is jlong type. When passed to sendfile, &offset is cast to off_t*. This will cause a lost of value on big endian machines.
> Since this value is guranteed to be inside scope of integer, we cast it to int before passing to sendfile to overcome this problem.
