You can resolve this issue by adding defaultValue like below.
@RequestParam(value = "version", required = false, defaultValue = "0") Integer versionNumber
see documentation

Unfortunately I cannot set a default value to the version (Application Logic). I'll have to handle the null in client itself. So I was wondering what turns my null object in client to string null when received in server.

actually it was a bug in previous versions which has been resolved now...try with latest versions defaultValue is not needed.

This was considered a bug in 2013: jira.spring.io/browse/SPR-10180 and was fixed with version 3.2.2. Problem shouldn't occur in any versions after that and your code should work just fine.
