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

Start with org.testcontainers.oracle.OracleContainer and the deprecated org.testcontainers.containers.OracleContainer, then inspect how the gvenzl/oracle-free and gvenzl/oracle-xe image names are validated. Determine whether both images should be supported by the Oracle module or split into vendor packages, and verify that migration from the deprecated package works for each image.
