Java: Some expressions have `<any>` as type

### Version

CodeQL CLI 2.11.4

### Description

Some expressions seem to have `` as type which is a CodeQL `Class` without any supertypes. Is that intended?

Example query:
```codeql
/**
* @kind problem
*/

import java

from Expr e
where e.getType().hasName("")
select e, "has as type"
```
