public class R42000XWIKI7726DataMigration
extends AbstractHibernateDataMigration

Migration for XWIKI-7726: Unable to delete attachments larger than 10 mb using the jetty + hsql distribution. Early versions of the HSQLDialect ignored the specified minimum length of LOB columns, creating them with the default length of 16M. Thus, the precision of existing CLOB and BLOB columns must be manually extended to the required 1G.

4.2M3
