Agreed. There's nothing indicating that 10.4 is worse than 10.3 in this
respect, so it shouldn't block the release. I just wanted to raise the
issue since bugs that cause database corruption are probably the worst
bugs a database system can have.

+1, sounds like a good idea. In the lack of reproducible test cases I
guess we'll have to focus on code review. If we think the corruptions
are caused by multi-threading bugs, using techniques like adding calls
to sleep() strategic places in the code (see DERBY-3393) could perhaps
also help us smoke them out.
