H2 does not appear to be supported.

[kaladay]

Some developers just need to spin up a Docker Container locally to perform tests.
Using H2 seems ideal in this case.

H2 appears to be unsupported because of the failure message below.

The fw build command is failing in mod-workflow when using H2.

$ fw build my-test-workflow
