> The constructors in FromNetASCIIInputStream.java assign a value to a static field:
> _lineSeparatorBytes = _lineSeparator.getBytes(encoding);
> This is not thread-safe, indeed it is thread-hostile if the value can ever be different for different encodings.
> (Two different instances wanting to use two different values of the same static field)
> The field should be initialised in the static initialiser (and should probably be made final as a hint not to change it - though this won't stop the contents being changed).
