Took me a few weeks, but I finally got around to installing a free
instance of Oracle (Express Edition 10.2) and testing the null handling
code we introduced in DbUtils 1.2 (DBUTILS-31).
Sure enough, there's a bug, DBUTILS-55, but I don't think it's very
important, since it's not a regression; it was there in DbUtils 1.1 and
nobody appears to have noticed or cared. :-) Also, I have no idea how we
could possibly fix it, since Oracle's JDBC driver doesn't support
ParameterMetaData.getParameterType.
With that done, and having tested successfully with Apache Derby, I'm now
prepared to give RC3 my +1. I believe we also already have a +1 from
Joerg Schaible, so we still need two more binding +1s to release.

RC3 includes an API change to QueryRunner to guarantee thread-safety.
(DBUTILS-52)
NOTE: No one has yet explicitly said on-list that they have tested DbUtils
1.2 with a real database. We should not release it until somebody tries it
out with a real live Oracle database, as described below.
Compatibility warnings:
* API change in QueryRunner: the setDataSource method was removed in order to
fix a thread-safety bug (DBUTILS-52)
* We upgraded the JVM dependency from JDK 1.3 to JDK 1.4 (DBUTILS-31)
* Users who may have extended BeanListHandler.handleRow will find that this
method no longer exists (is no longer called) in DbUtils 1.2 (DBUTILS-37)
* Users who may have extended KeyedHandler will find that its protected
members are now final (to guarantee thread safety). (DBUTILS-51)
PLEASE TEST THIS RELEASE WITH A REAL DATABASE!
Although this project has reasonable unit tests, it has no integration tests
with any actual databases; it is quite possible that the fix for DBUTILS-31
has broken something on Oracle, MS SQL Server, Derby, or your favorite
database.
To verify DBUTILS-31, use QueryRunner to put a null value in a field, e.g.
with QueryRunner.update. Ideally it would be good to verify putting nulls in
fields of various types: char, varchar, int, boolean, date, etc.
