unrecognised option '--noprealloc' with Spring Boot 2.6.2 and de.flapdoodle.embed.mongo 3.2.7

Hi, I am upgrading from Spring Boot 2.5.8 to 2.6.2. Since now the property spring.mongodb.embedded.version is mandatory, I am annotating my test (in a Maven multi-module project) with:

@DataMongoTest(properties = {
    "spring.mongodb.embedded.version=5.0.1"
})

but I have a Caused by: java.lang.RuntimeException: Could not start process: <EOF>

I debugged it, and seen that Mongo is started with this command:

/var/folders/rg/1n7z661961s444dbs1cw3s380000gq/T/extract-1d38d22e-0012-4abf-ba43-3e872d888de9extractmongod --dbpath /var/folders/rg/1n7z661961s444dbs1cw3s380000gq/T/embedmongo-db-a8b668e5-4944-4198-84e6-75067c3fa79a --noauth --noprealloc --smallfiles --nojournal --nohttpinterface --port 60078 --bind_ip 127.0.0.1

which, when manually started, fails with the following errors: Error parsing command line: unrecognised option '--noprealloc' Error parsing command line: unrecognised option '--smallfiles' Error parsing command line: unrecognised option '--nohttpinterface'

I am currently running it on a x86 Mac, but this should run on all environments. Is there any Spring Configuration property to set these?

@xiaodongli7 hmm… did a new release… 5.0.5. should work now, but i suspect that the way spring integrates embed mongo is responsible for these issues…

@xiaodongli7 maybe 4.4.9 may work too… i think it depends if a version is in this list: https://github.com/flapdoodle-oss/de.flapdoodle.embed.mongo/blob/master/src/main/java/de/flapdoodle/embed/mongo/distribution/Version.java
