Description

For Eclipse memory analyzer plugin it is required to process references somehow, enable navigation (e.g. `where emp.manager.manager.name='boss'`)

Currently `StackOverflowError` occurs when trying self-referencing data type (see relevant code at https://github.com/julianhyde/optiq/blob/450562d268d37e8b24421117d1834e5b8dffdda4/core/src/main/java/net/hydromatic/optiq/jdbc/JavaTypeFactoryImpl.java#L60)

```java
class Employee {
Employee manager;
...
}
```

`StackOverflowError`
