I just came across this problem working with the JSONB column type - the binary version of the JSON type, which doesn't map to TEXT.

For future reference, you can define a custom type in H2 using CREATE DOMAIN, as follows:

This seemed to work for me, and allowed me to successfully test my code against the entity.
