There is no problem with 1+"" neither with new Integer(1)+"" in Java. Nor
any other object on the left hand side. The + operator is not tied to the
left hand side as in C++. if either side is a string and the other side has
a toString method it is OK. This is special-cased in the compiler. It is
defined in the language definition, not in the library definition.
