Spring Boot processAot fails with ojdbc library in place

NOTE: This comes from https://github.com/spring-projects/spring-boot/issues/50623 which suggests to open the ticket here instead

With Spring Boot 4.x, having the com.oracle.database.jdbc:ojdbcX dependency in the project results in a failure to run the processAot task.
I'm specifically on com.oracle.database.jdbc:ojdbc11:23.26.2.0.0, but it happens with ojdbc17 as well.
This same library on Spring Boot 3.x isn't causing any issues.

Trying to work around it by adding com.oracle.database.ha:simplefan:23.26.2.0.0 just compounds on the issue as it then breaks and demands for another library, com.oracle.database.xml:xdb:23.26.2.0.0, which then breaks and demands for yet another, and so on and so forth -- all on libraries that I explicitly do not want on the project.

This is tested on Open JDK 17 and 21, both having the same issue.
I'm mentioning the JDK flavor here in particular because it seems Quarkus had a somewhat-similar issue in the past and blamed that, but this didn't help me here -- https://github.com/graalvm/mandrel/issues/252
