--------------------------------------------------------------------
that is a good point .. i checked back on this ..
In Bytes.java we are using this for the littleEndian check .. this is
evaluating to true for me on my dev/prod box
static final boolean littleEndian =
ByteOrder.nativeOrder().equals(ByteOrder.LITTLE_ENDIAN);
ByteOrder.nativeOrder()
Retrieves the native byte order of the underlying platform.
echo -n I | od -to2 | head -n1 | cut -f2 -d" " | cut -c6
1
So looks like it is using the machine endianess?

Although from what i read online java is supposed to be bigendian .. will check
on this also
