Hi,

I think this issue was resolved in version 1.4.179, see the changelog entry:

   - Databases created with version 1.3.175 and earlier that contained
   foreign keys in combination with multi-column indexes could not be opened
   in some cases. This was due to a bugfix in version 1.3.176: Referential
   integrity constraints sometimes used the wrong index.

I suggest to use a recent version of H2, but append ";mv_store=false" to
the database URL.

Worst case, you would need to export the database to a SQL script with an
old version, and re-created it from the script in the new version.

Regards,
Thomas
