CompositeUserType was reworked in Hibernate 6.0 so this is definitely not an issue anymore.

As part of verifying that this issue affects 5.0, please just set the "Affects version". Leave the "verify-affects-5.0" label and leave the issue in "Awaiting Response" status; these are critical for us to be able to track these verifications and triage them. Thanks.

This bug report does not indicate that the reported issue affects version 5.x. Versions prior to 5.x are no longer maintained. It would be a great help to the Hibernate team and community for someone to verify that the reported issue still affects version 5.x. If so, please add the 5.x version that you verified with to the list of affected-versions and attach the (preferably SSCCE) test case you used to do the verification to the report; from there the issues will be looked at during our triage meetings.

When trying to register a Composite UserType in a Integrator via configuration.registerTypeOverride, the creation of the entityManager fails while validating the mapping of such a type with a MappingException: "mapping has wrong number of columns" (see full stack trace below). The problem seems to be, that the registered type is not available in the TypeRegistry while doing this check, so the type is broken down to SerializableType, for which only one column is expected, not several columns as defined in the CompositeType. I tested this with the Jadira UserTypes, but initially had this bug with my own Composite UserType.
I'll attach a small test case which reproduces the mentioned issue.
