Our current type matcher does not work anymore in a Spring Criteria project because criteria expressions from Spring boxes any primitive type in a Java object type and which then is not assignable to a detected primitive type from the parsed schema.

Example:

Consider the following schema

and the following spring query

where(age).is(30)

in normal world this should work but because is call converts the provided Int primitive to a Java Object type the resulting BsonType is a BsonAnyOf(BsonInt32, BsonNull) and this is not assignable to the age field which is only expecting BsonInt32
