After migrating from Hibernate 5.6.14 to 6.1.6, I am encountering a schema validation
error:
Exception in thread "main"
org.hibernate.tool.schema.spi.SchemaManagementException: Schema-validation: wrong column
type encountered in column [name] in table [Foo]; found [longtext (Types#LONGVARCHAR)],
but expecting [tinytext (Types#CLOB)]

I reproduced the bug with the example below (for more convenience, I also zipped and
attached the project).
It requires a table in MySQL:
CREATE TABLE foodb.Foo (id INT , name LONGTEXT );
