Description
The Issue is:
-When running the application (spring data mcr.microsoft.com/mssql/server:2019-CU8-ubuntu-16.04) with a docker container everything worked as expected.
-When running the application with testcontainers the tables stayed locked (using the same image all the time).
-When removing the crudRepository from Spring Data in the test and using the raw entity manager the tables locked (the test could pass because of the persistence context of hibernate).
-When using raw JDBC the test worked fine.
I'm using Junit 5, testcontainerVersion 1.14.3 and Hiberante core 5.4.21.Final (spring boot version2.3.4.RELEASE).
I don't really know if this is an Hiberante or a testcontainers issue, because Hibernate did work normally with docker, but started locking tables with when testcontainers got involved.

Research direction
No repository files or specific test entry points are named. Start by reproducing the JUnit 5 test with Testcontainers 1.14.3, Hibernate 5.4.21.Final, Spring Boot 2.3.4, and the stated SQL Server image, then compare CrudRepository, raw EntityManager, and JDBC behavior; done means identifying whether Testcontainers or Hibernate causes the table locks and documenting a verified resolution.
