NPE in PropertyValueConverterFactory.getConverter

[loonis]

• Using spring-data-commons-2.7.0-M4 (via Spring boot 2.7.0-M3)
• In a multithreaded context where I read and insert thousand of document in Mongodb

Arround 1% of my reads fails due to the error below. If I retry the read few seconds later it passes.

I tried with spring-boot:2.7.0-M2 (spring-data-commons-2.7.0-M3) and there is no error.
I also tried with spring-data-commons-2.7.0-M4 (via Spring boot 2.7.0-M3) in a single sequential thread, there is no error too.

Caused by: java.lang.NullPointerException: Cannot invoke "org.springframework.data.convert.PropertyValueConverterFactory.getConverter(org.springframework.data.mapping.PersistentProperty)" because "this.converterFactory" is null
