Now I got the solution.
It was very close to what Thomas suggested, but I had to build a byte array :
// Create the identifier
UUID id = UUID.randomUUID();
String stringId = id.toString();
stringId = stringId.replace("-","");
// Create the byte array based on the hexadecimal key
byte[] byteKey = new byte[16];
int byteindex = 0;
for(int c = 0 ; c < 31 ;){
int fim = c + 2;
int myB = Integer.parseInt( stringId.substring(c,fim), 16);
byteKey[byteindex] = (byte) myB;
++byteindex;
c = c + 2;
}
// Create the COSString IDs based on the byte array
COSString ID1 = new COSString(byteKey);
COSString ID2 = new COSString(byteKey);
// Create the array with both keys ( in my case the same for both )
COSArray myAL = new COSArray();
myAL.add(ID1);
myAL.add(ID2);
// Set the new IDs in the document
myPdf.getDocument().setDocumentID(myAL);
