Postgres 7.3b1 + JDBC3 (2002-09-05) truncates SQL commands?

hi

i have a very wired problem.
when i try to execute the following SQL command:

INSERT INTO SERIES
(seriesDateTime,modality,seriesnumber,seriesinstanceuid,seriesdescr,bodypartexamined,slicethickness,sequencename,viewdirection,studytype,fieldofview,contrastAgent,numberseriesrelatedimages,manufacturermodel,stuParent,insertTimestamp)
VALUES ('2002-05-07 14:34:12.0', 'MR', '2',
'1.2.804.114118.1.20020507.143415.2812940098.1.1', 'SCRAPBOOK', '',
'006.000000E+00', 'b0_1000', 'HEAD', 'MEA', '261*261', '', 0, 'MAGNETOM
Harmony', '1.3.12.2.1107.5.2.5.10288.20020426150938000', '2002-09-17
11:07:30.293');

via the JDBC3 beta driver for postgres 7.3b1 i get the following error.

2002-09-17 11:07:30 [24588] LOG: query: INSERT INTO SERIES
(seriesDateTime,modality,seriesnumber,seriesinstanceuid,seriesdescr,bodypartexamined,slicethickness,sequencename,viewdirection,studytype,fieldofview,contrastAgent,numberseriesrelatedimages,manufacturermodel,stuParent,insertTimestamp)
VALUES ('2002-05-07 14:34:12.0', 'MR', '2',
'1.2.804.114118.1.20020507.143415.2812940098.1.1', 'SCRAPBOOK
2002-09-17 11:07:30 [24588] ERROR: parser: unterminated quoted string

2002-09-17 11:07:30 [24588] LOG: statement: INSERT INTO SERIES

'1.2.804.114118.1.20020507.143415.2812940098.1.1', 'SCRAPBOOK

it seems as if the SQL command was truncated.
i added and removed some spaces to the command. it is always trunctated
ryt where the ' behind SCRAPBOOK is supposed to be.
so it doesn't seem to be some fixed character number (i.e. due to some
undersizes buffer) after which the statment is truncated.
the exact same programm/statment works on an IBM DB/2 db without
problems, btw.

I was wondering if this is maybe a known problem in the 7.3b1 release of
postgresql or the beta jdbc driver.
