This bug might be related to [ https://hibernate.atlassian.net/browse/HHH-13712 |https://hibernate.atlassian.net/browse/HHH-13712]

* Whats the issue?*
If you run the [ http://localhost:8080/subobj, |http://localhost:8080/subobj,] the select query generates fine. But the count query doesn't contain JOIN statement so making the ' where ( subobject0_1_.DELETED = 0)' clause invalid.

```sql

Hibernate: {noformat}// select query --- is valid
select subobject0_.id as id1_1_, subobject0_1_.deleted as deleted2_1_, subobject0_.age as age1_0_, subobject0_.name as name2_0_ from sub_object subobject0_ inner join super subobject0_1_ on subobject0_.id=subobject0_1_.id where ( subobject0_1_.DELETED = 0) limit ?

Hibernate: //count query does't have join
select count(subobject0_.id) as col_0_0_ from sub_object subobject0_ where ( subobject0_1_.DELETED = 0) {noformat}
```

Which results in following exception:
```
{noformat} org.h2.jdbc.JdbcSQLSyntaxErrorException: Column "SUBOBJECT0_1_.DELETED" not found; SQL statement:
select count(subobject0_.id) as col_0_0_ from sub_object subobject0_ where ( subobject0_1_.DELETED = 0) [42122-200] {noformat}
```

* How to reproduce:*
Clone and run [ https://github.com/gtiwari333/hibernate-inheritance-JOINED-with-where-bug |https://github.com/gtiwari333/hibernate-inheritance-JOINED-with-where-bug] then  open [ http://localhost:8080/subobj |http://localhost:8080/subobj] on your browser

* Notes:*

* - It appears the issue is only with   InheritanceType.JOINED. Other types works fine (see ``bug.entity.Super.java``)
*
* No issue when hibernate.version = 5.4.4.Final
