I'm getting an error, org.h2.jdbc.JdbcSQLNonTransientException: General 
error: "java.lang.NullPointerException", when trying to run an integration 
test that uses an H2 in-memory DB. The error only occurs with H2, not when 
running the same query against a Postgres instance. Any thoughts on 
resolving this issue?
