I found the problem: the parameter list is inverted with this kind of
method call:

Variant result = propertiesAutomation.invoke("add", new Object[]{
                 Variant.createUnspecifiedParameter(), //LinkToSource
                 new Variant(100), //Value
                 new Variant(4), //Datatype 1-number, 2-Boolean, 3-Date,
4-String, 5-Float
                 new Variant(false), //LinkToContent
                 new Variant("m2n uri") //Name der Property
         });
