I'm running into an issue with a Spring Boot service running unit tests using JUnit5 and flapdoodle's embeddedMongo. My unit tests were running fine previously, both locally and in Jenkins. I'm trying to update to Java 17 and Spring Boot 2.6.3, and that's where I'm running into issues. With the latest version of embeddedMongo, my unit tests run fine locally, but when I upload them to Jenkins, the first test always fails (with subsequent tests succeeding) with the following logs:

It looks like the embedded database is still downloading while the first test is running, but is in place for later tests. I've tried changing the order of tests, but got the same behavior, so it's not the specific test that runs first, it's the timing.
My tests are WebMvcTests with mongo autoconfigured:
@ExtendWith(SpringExtension.class)
@ContextConfiguration
@AutoConfigureDataMongo
@WebMvcTest(
controllers = {
AccessorialTypeController.class,
AccessorialTypeDao.class,
ServicePermissionEvaluator.class,
MethodSecurityConfig.class,
APIExceptionHandler.class,
PatchValidator.class
},
properties = {
"spring.mongodb.embedded.version=3.5.5"
})
I've tried a number of different embedded versions, and this is the closest I've gotten it to running. Later versions result in all of the tests failing with similar but not identical file not found exceptions, not just the first.
