ArrayStoreException in Constraint.generateName

Description

I have the following mapping inside an entity:

When I start the application the following exception occurs:

This is, because Table.generateName(List keyColumns) is called with a list that contains a Column and a Formula object. Inside that method org.hibernate.mapping.Constraint#generateName(java.lang.String, org.hibernate.mapping.Table, java.util.List<org.hibernate.mapping.Column>) is called:

The call columns.toArray(new Column[columns.size()]) causes ArrayStoreException because an array for Column is initialized, but the columns list also contains a Formula object.

I'm using spring 5.1.7, spring boot 2.1.5, spring-data 2.1.8, hibernate-core 5.3.10.Final
