I’m using hibernate.hbm2ddl.auto=update to change a varchar column to another length but it does not work with hibernate 6.3.1. I’ve debugged the hibernate code and I think the method IsStringType(int typeCode) in org.hibernate.type.SQLTypes is wrong. It always return false. The source code for this method in hibernate 6.4.0 is the same. Am I wrong or is this a bug?

Regards,  
Thomas
