What happened?

Containers under package org.testcontainers.containers are deprecated and should be migrated to org.testcontainers.<vendor> in Testcontainers 2.

For Oracle Module at org.testcontainers.oracle.OracleContainer the migration is not possible for gvenzl/oracle-xe image and org.testcontainers.containers.OracleContainer has to be used.

Either org.testcontainers.oracle.OracleContainer should support both xe and free or they should have their own vendor package.

Relevant log output

java.lang.IllegalStateException: 
Failed to verify that image 'gvenzl/oracle-xe' is a compatible substitute for 'gvenzl/oracle-free'. This generally means that you are trying to use an image that Testcontainers has not been designed to use. If this is deliberate, and if you are confident that the image is compatible, you should declare compatibility in code using the `asCompatibleSubstituteFor` method. For example:
   DockerImageName myImage = DockerImageName.parse("gvenzl/oracle-xe").asCompatibleSubstituteFor("gvenzl/oracle-free");
and then use `myImage` instead.

Additional Information

No response

Inizia con org.testcontainers.oracle.OracleContainer e con il deprecato org.testcontainers.containers.OracleContainer, quindi esamina come vengono convalidati i nomi delle immagini gvenzl/oracle-free e gvenzl/oracle-xe. Determina se entrambe le immagini debbano essere supportate dal modulo Oracle o suddivise in pacchetti dei vendor, e verifica che la migrazione dal pacchetto deprecato funzioni per ciascuna immagine.
