CMT - Does not like to port some tables from database - keyword problem?

I have MySQL database with the following two tables

CREATE TABLE `jm_finder_tokens` (
`term` varchar(75) NOT NULL,
`stem` varchar(75) NOT NULL,
`common` tinyint(1) unsigned NOT NULL DEFAULT '0',
`phrase` tinyint(1) unsigned NOT NULL DEFAULT '0',
`weight` float unsigned NOT NULL DEFAULT '1',
`context` tinyint(1) unsigned NOT NULL DEFAULT '2',
KEY `idx_word` (`term`),
KEY `idx_context` (`context`)
) ENGINE=MEMORY DEFAULT CHARSET=utf8

CREATE TABLE `jm_finder_tokens_aggregate` (
`term_id` int(10) unsigned NOT NULL,
`map_suffix` char(1) NOT NULL,
`term` varchar(75) NOT NULL,
`stem` varchar(75) NOT NULL,
`common` tinyint(1) unsigned NOT NULL DEFAULT '0',
`phrase` tinyint(1) unsigned NOT NULL DEFAULT '0',
`term_weight` float unsigned NOT NULL,
`context` tinyint(1) unsigned NOT NULL DEFAULT '2',
`context_weight` float unsigned NOT NULL,
`total_weight` float unsigned NOT NULL,
KEY `token` (`term`),
KEY `keyword_id` (`term_id`)
) ENGINE=MEMORY DEFAULT CHARSET=utf8

When I try to use CMT to migrate those two tables, I get the following errors:

Index "idx_word" in table "jm_finder_tokens": Full text index is not supported in CUBRID.
Index "token" in table "jm_finder_tokens_aggregate": Full text index is not supported in CUBRID.

Details:
mysql> desc jm_finder_tokens;
-----------------------------------------------+

-----------------------------------------------+

-----------------------------------------------+

mysql> desc jm_finder_tokens_aggregate;
------------------------------------------------------+

------------------------------------------------------+

------------------------------------------------------+
10 rows in set (0.00 sec)

There are no full text indexes on those tables. So I guess it's a bug?
