Hm, but this also doesn't check how many bytes were actually read?

yep, but readFully will either block until the full number of bytes is available, or throw an error:
http://docs.oracle.com/javase/6/docs/api/java/io/DataInput.html#readFully(byte[])

// update our current position
currentPosition = currentPosition + recordLength
// return true
