Hi,
a customer of mine had some random crash which left the h2 1.0.79
database corrupted.
Recovery works, but a lot of data is missing.
When opening _without_ recovery turned on, I get this trace entry:
java.lang.RuntimeException: Unexpected code path

I guess the data is simply gone.
No, this isn't the first time an h2 1.0.79 database got corrupted due
to program crashes.
What I am wondering is, how can I better avoid data loss (except for
backing it up, of course)?
Would upgrading to the latest h2 1.1 be beneficial at all?
In other words, is this is problem that has been fixed already?
Thanks,
