Hi all!

I use hibernate 2.1.4 on Linux with a MySQL 4.0.18 server. When I try to use the schema update tool then I get the following messages:

[schemaupdate] INFO: processing foreign key constraints
[schemaupdate] alter table HIB_ROLE_PROJECT_TIMESHEET add index FKC9EF7BE12A15E434 (FOREIGN_KEY), add constraint FKC9EF7BE12A15E434 foreign key (FOREIGN_KEY) references HIB_ENTITY_TIMESHEET (id)

...

Does anyone know how to fix or work around this?
