>
> When trying to register a SqueezeAdaptor with a prefix that is already used
> by another registered SqeezeAdaptor, the error message says:
> "An adaptor for prefix '' is already registered."
> i.e. it does not specify _which_ prefix is already registered. The Exception
> in DataSqueezerImpl.register(SqeezeAdaptor) is thrown as follows:
> if (_adaptorByPrefix[offset] != null)
> throw new IllegalArgumentException(Tapestry.format(
> "DataSqueezer.adaptor-prefix-taken",
> Character.valueOf( prefix.charAt(i) ) ));
> prefix.substring(i, i)));
> Fix suggestion: The call to prefix.substring(i, i) should be replaced with
> prefix.substring(i, i+1)
> (see
> http://java.sun.com/javase/6/docs/api/java/lang/String.html#substring(int,%20int)
> )
