In a POJO if you have a field or method that is marked with @BsonIgnore , and if this is a type disallowed by the TypeData$Builder the class model creation will fail - despite this field / method not being required.
Example exception
java.lang.IllegalStateException: Invalid Map type. Maps MUST have string keys, found class com.TestEnum instead.

Here the pojo contains a Map keyed on an enum. This map is marked with @BsonIgnore, hence I would not expect the failure above.
