That just works when compiling on jdk1.3 and will not work on jdk1.3 when
compiled on jdk1.4
To prevent this, you specifically have to cast it to object to say "use the append which takes an
object" or as Nicolas suggested a toString(), but the last one is not my favorite solution..

StringBuffer has a new method in Java 1.4 to append another Stringbuffer
without invoking it's toSring() method.
Code that uses StringBuffer.append(stb) and compiled by a JDK 1.4 will
not work on Java 1.3.
I miself recommand Using "StringBuffer.append(stb.toString())" that
looks better than an apparently useless (Object) cast : checkstyle or
IDE may warn for unecessary cast.
But that won't work so well on Java 1.4+.
Can't one just use:
sb1.append(sb2);
for both 1.3 and 1.4, and let the method do the work as needed?
