quote.sql.identifiers

i am using dbz connector to go from pgsql to oracle:

the source connector is debezium

the sink connector is from debezium/connect:1.2.4.Final

objects (table,column,schema) in pgsql are in lower case.
objects in oracle are in uppercase.

i have set quote.sql.identifiers to never, see desc:
curl -X POST -H "Content-Type:application/json" kafka-connect.kafka:8083/connectors -d '{
"name": "oradbname_newtable_sink",
"config": { "connector.class": "io.confluent.connect.jdbc.JdbcSinkConnector", "key.converter": "io.confluent.connect.avro.AvroConverter", "key.converter.schema.registry.url": "myurl", "key.converter.basic.auth.credentials.source": "USER_INFO", "key.converter.basic.auth.user.info": "user:pwd", "value.converter": "io.confluent.connect.avro.AvroConverter", "value.converter.schema.registry.url": "myurl", "value.converter.basic.auth.credentials.source": "USER_INFO", "value.converter.basic.auth.user.info": "user:pwd", "delete.enabled": "true", "tasks.max": "1", "quote.sql.identifiers": "never", "topics": "mytopic.myschema.mytable", "table.name.format": "DBZMD.MYTABLE", "dialect.name": "OracleDatabaseDialect", "connection.url": "myoracle_srv", "connection.user": "DBZMD", "connection.password": "pwd", "transforms": "unwrap", "transforms.unwrap.type": "io.debezium.transforms.ExtractNewRecordState", "transforms.unwrap.drop.tombstones": "false", "insert.mode": "upsert", "pk.mode": "record_key", "pk.fields": "id" }
}'
