I occasionally get an exception from H2 with "Unexpected code path".
It's not easily reproducible in my application, and I don't have a
concise test program to demonstrate it, but I've excerpted the stack
trace in hopes that it's enough to figure out the bug.
I'm using H2 1.0.77, which is being called through a product called
Sequoia - you can ignore the parts of the stack trace below which are
from Sequoia.

Does this help?
Thanks,
