Database schema/table prefix - spring process engine config

Attempting a migration from activiti 5.21.0 to Flowable 6.7.2 - using the custom configuration pattern from the spring boot docs, I’m setting the schema for our oracle db and trying to use that schema as the table prefix -

public class MyConfigurer implements EngineConfigurationConfigurer<SpringProcessEngineConfiguration> {
    ...
    public void configure(SpringProcessEngineConfiguration processEngineConfiguration) {
        processEngineConfiguration.setDatabaseSchemaUpdate(schemaUpdate);
		processEngineConfiguration.setDatabaseSchema(databaseSchema);
		processEngineConfiguration.setDatabaseTablePrefix(databaseSchema + ".");
		processEngineConfiguration.setTablePrefixIsSchema(true);
		processEngineConfiguration.setDeploymentName(deploymentName);
		processEngineConfiguration.setFlowable5CompatibilityEnabled(flowable5Compatibility);
		processEngineConfiguration.setFlowable5CompatibilityHandlerFactory(springFlowable5CompatibilityHandlerFactory());
    }

}

The engine is failing the migration of the flowable schema for an insert into ACT_GE_PROPERTY, which is not being found for the insert. The prepared sql statement is missing the schema, i.e. I am getting

insert into ACT_GE_PROPERTY values ('common.schema.version', '6.2.0.0', 1)

where I think I should be getting

insert into MY_DB.ACT_GE_PROPERTY values ('common.schema.version', '6.2.0.0', 1)

Digging into the spring configuration setup, I find my configurer associated with the other autoconfigurers when the engine starts, but the prefix/schema value appears to be getting overwritten by an autoconfiguration. What am I missing?

For Oracle, that should be enough. The schema is set on the JDBC level and all SQL statements are done implicitly in that schema (that’s also how we’ve configured our QA tests for running against a specific Oracle schema). How does the jdbc url looks like? What config were you using with activiti?
