Java: Member.getQualifiedName does not use qualified name of declaring type

**Description of the issue**
Slightly related to #3604

It appears `Member.getQualifiedName` does not use the qualified name of the declaring type, but instead only the simple name, e.g.:
```
Integer.MAX_VALUE
```
instead of
```
java.lang.Integer.MAX_VALUE
```
In case this is intended, it would be good if that was documented because normally you would expect the qualified name of the declaring type to be used.
