Ouch that is nasty :O

But are we sure that h2 doesn't work with jdbc 4.2? I mean, how does it work otherwise with java8 anyways? I'm a bit confused about that. Are people required to replace their jdbc driver with an older version when they run geoserver on java8? Or am I missing something?

    h2 1.1.119, is an old version -> might need to upgrade to newest,
    then it should work with 4.1 and 4.2


Upgrade is a major can of worms, that's why we haven't upgraded yet...
The database format of the latest versions is unfortunately incompatible.
Basically, you'll need to find a way to transparently upgrade the H2 databases of all existing data directories (last time I looked
I could not find a transparent upgrade tool, it may need to be built).

H2 is being used, going by memory, for disk quota, for KML superoverlays, for NetCDF indexes, jdbconfig,
maybe monitoring too... am I forgetting anything?
All of them are not quite visible to users, and all need a safe upgrade path if you change the H2 version (and instructions to backup everything, because going back won't be possible).

Cheers
