I think you are correct, but I also have a very vague memory of some issues if we didn't use the &'s. I know this is early code and we (Cloudscape engineers) were following the examples from Sun, e.g. look at this extract from the Javadoc for java.io.DataOutput.writeShort.
http://java.sun.com/j2se/1.4.2/docs/api/java/io/DataOutput.html#writeShort(int)
The byte values to be written, in the order shown, are:
~ (byte)(0xff & (v >> 8)) ~ (byte)(0xff & v)
