Tablespaces not generated with generateChangeLog on DB2

I have a database which contains a table, linked to a tablespace.
When I execute the commande line liquibase generateChangeLog with the --include-tablespace=true , there is no tablespace attribute in the createTable section of the generated changeLog.

I use DB2
