No, the problem was that I tried to use the OPS4J DerbyDataSourceFactory to create a connection for a derby client JDBC URL[1], and the DerbyDataSourceFactory can't do that, because it creates a derby EmbeddedDataSource[2]. And an EmbeddedDataSource can't create a client connection. That's why things failed. So let the test create a client connection using the regular API[3], and then the test ran fine, and was able to output the liquibase stuff to a running derby container.
