I have an spring batch application which is recently been migrated to springboot v3 , spring batch v5 and jdk 17 . The application works fine but I am facing an issue related to Hikari pool connection whenever some Testcases are executed . We have a db update operation in afterJob method of JonExecutionListener and the Hikari error is coming when the db operation is executed in afterJob.
Error we are getting :
org.springframework.jdbc.CannotGetJDBCConnectionException:Failed to obtain JDBC connection .,
caused by : HikariDatasource HikariDatasource(HikariPool-3) has been closed.

I can see some warning as well -
Hikari pool -1 Connection oracle.jdbc.driver.T4CConnection@663dd728 markes as broken because of SQLSTATE(08006), ErrorCode (17002)

Testclasses are written as 👍

@ExtendWith(SpringExtension.class)
@SpringBootTest
@activeprofiles("junit")
public class TestClassA
{
@Autowired
private BatchJobRunner batchRunner;

@test
private void testMethod(){
batchRunner.runJob();

}
}
}
