DERBY-6542 changed IDENTITY columns to build upon the underlying
SEQUENCE objects. SEQUENCE objects can have a CYCLE option
set for them, and as of
DERBY-6852, the CYCLE option controls the
behavior of the IDENTITY column that uses that SEQUENCE.
It would be nice if SYS.SYSCOLUMNS would report the CYCLE option
that is in effect for a IDENTITY column in that column's row in SYSCOLUMNS.
