https://gist.github.com/wildy/16415fa756d2073a2d3f8e8170646888 Seems like I got hit by a bug where Exposed can't find the table if using a newer H2 version that defaults to being case-sensitive. But applying the suggested workaround doesn't fix it. Where did I screw up this time? 🙂 (and excuse me, I've been sitting here for um... almost 16 hours straight, redid almost everything but now can't get it to work because of the db)

Have you tried the following with named parameters?

Database.connect("jdbc:h2:mem:test", driver = "org.h2.Driver", user = "root", password = "")

Not sure if you have managed to connect already or if it's something new. You could also try this.

Database.connect({ DriverManager.getConnection("jdbc:h2:mem:test;"EXTRA CONFIG") })

If neither of these work you could also check out https://github.com/openbouquet/HikariCP

There are a lot of other issues with h2 version 1.4.200 that's why Exposed still tested only against 1.4.199. One of the critical issues is https://github.com/h2database/h2database/issues/2191
