NPE at net.datafaker.service.FakeValuesService.fetchObject():268 #1412
Description
Describe the bug
java.lang.NullPointerException: Cannot invoke "java.util.Map.get(Object)" because the return value of "net.datafaker.internal.helper.CopyOnWriteMap.getOrDefault(Object, Object)" is null

Similar, but not identical to #1403 which was resolved in 2.4.1.
To Reproduce
Failure is intermittent and probably due to a concurrency issue when running multiple tests in parallel which all try to initialize datafaker at the same time
Expected behavior
No NPE
Versions:
- OS: Win 11 x64
