Vraimente.

java.util.Map map = con.getTypeMap();

So, the variable "map" is now an empty map object. Highly likely it
contains hex zeroes. It could contain the string "empty" but that does
not sound reasonable. Maybe there is no memory address and memory is
only allocated with the first "put".

System.out.println("map:"+map);

So, println accesses the memory occupied by the object and assuming it
contains unprintable hex zeroes, it can either display "null", or
convert to printable zeroes or ignore it and display nothing.

What output did you expect from  "System.out.println("map:"+map);"??
That is the question.
