Schema generation is using this query to create test table on Derby:

INFO: CREATE TABLE TYPES_MAPPING_TEST1
(AAAID INTEGER NOT NULL,
BIT_COLUMN SMALLINT,
BOOLEAN_COLUMN SMALLINT,
TINYINT_COLUMN SMALLINT
PRIMARY KEY (AAAID))

Why everything is mapped to SMALLINT?
There is BIT, BOOLEAN and TINYINT types in Derby.
