Unfortunately I cannot reproduce this problem. Actually the
JDBCCursorWrapper (doj/db/backends/__init__.py) overrides the rowcount
propertry of zxJDBC to return updatecount instead of rowcount, if it is
bigger.

Could you please check if the __get_rowcount method in JDBCCursorWrapper is
ever reached?

What version of the SQLite JDBC driver are you using? I have
sqlite-jdbc-3.7.15-SNAPSHOT-f18 on my machine.
