Is F9065 and F98305V tables really need for successful JAS objects generation?

Hello, List!
I install JAS on 2000 Server(+3SP) and Websphere 3.5+6SP.
I generate objects on Generator machine via JAS more than one time. I receave a lot of errors in generror.log (same as "Retrieving PO template in application R49101 failed"). When I serialize Core objects I receave two errors in generror.log:
[ 2002-11-12 13:40:04.677 ] Table F9065: JNIGEN: Failed to get table specs in FetchTableHeader
[ 2002-11-12 13:40:04.717 ] Could not generate: F9065
[ 2002-11-12 13:40:04.797 ] Table F98305V: JNIGEN: Failed to get table specs in FetchTableHeader
[ 2002-11-12 13:40:04.827 ] Could not generate: F98305V
I really haven't theese tables. Should I install ESU jd12204 (F9060, F9065, F9066) and jd15742 (F98305V and other)?

I search information about theese tables on KG. Theese tables appear from Update 4, but I apply only Update 2.
Do I need apply ESUs with theese tables?
