The code previously submitted was invalid.
Should be:

/// PASS
    StringBuffer joinLn( String[] list, StringBuffer buf = new 
StringBuffer(), int from = 0 )
     = from < list.length ? joinLn( list, buf.append( list[ from ] ).
append( '\n' ), from + 1 ) : buf;

But this correct code produces the same compiler exception.
