Yes, please. It has been some misunderstanding. If I understood clearly,
there are two bugs:

1) Java 7 not recognized
2) Java versions recognized but being suboptimal with Base + JDBC


(1) happens only on Windows, mostly Windows 7 64 bits. I haven't seen
any report of this happening on Linux 32/64 bits, and if I understood
you clearly, neither could you reproduce it

(2) happens on Linux and Windows, both 32 and 64 bits. This is
a performance issue with Base+JDBC. If a user does not need Base/JDBC at
all, she/he can still use Java 7 for the Letter/Fax/Agenda wizards,
extensions, etc. (I haven't seen performance reports in these areas).


Side comment, it should be noticed that there is no need to actually
*install* Java 6, you can unzip a JRE anywhere and then point OpenOffice
to use it, and things work just fine (assuming you didn't mess with
environment variables, etc.). This works both on Linux and Windows; that
said, I've no idea if Oracle is providing un-installable, zipped
versions.

I have been told [1] that Stephan Bergmann solved this issue in LO,
unfortunately he's been payed by RedHat to work there, so there are no
many chances to see the patch contributed here (though he is committer
for this project).
