First, Andreas, thanks for providing these issue numbers and saving us the
trouble of locating them.

OK, if I am wrong, I am wrong, I accept that. My testing with java 7 so far
did not yield any problems but I did not use a jdbc connection to anything.

Which brings me to a few items of note on jdbc:
* java 7 implements jdbc 4.1, java 6 implements 4.0 if I'm not mistaken
* an appropriate connector that recognizes/uses jdbc 4.1 must be obtained
for the DB you are using.

So, there items that need further investigation on both the AOO side
(client ), and connectivity side (the receiving DB and what it's using).

I am not familiar at all with HyperSQL (hsqldb) and don't know if it runs
under java 1.7.
