this is a demonstration of what seems to be a bug in the micronaut-jdbc-dbcp module.

project creation command: mn create-cli-app -i --jdk=17 -l=java -t=junit -b=maven -f=data-jdbc,jdbc-dbcp bugReport1

command to expose the bug: mvn test

the test passes, but context destruction throws:

Error destroying bean of type [class io.micronaut.configuration.jdbc.dbcp.DatasourceConfiguration]: class io.micronaut.transaction.jdbc.TransactionAwareDataSource$DataSourceProxy cannot be cast to class io.micronaut.configuration.jdbc.dbcp.DatasourceConfiguration

the newest micronaut-data-jdbc available as of now pulls in micronaut SQL libraries at version 4.0.0-RC4, but even upgrading them to the newest, 4.1.1, doesn't help.

raised as an issue.
