Simple testcase for a query bug in spring-data-mongodb QueryMapper with annotations and PropertyValueConverter.
The @LocalDateAsString annotation is used on selected LocalDate fields to have them mapped to string in mongo.
The LocalDateToStringPropertyConverter simply converts to/from String/LocalDate.
Everything is fine with mapping and simple queries but with eg "range" queries the QueryMapper calls the converter with a bson Document which obviously fails with a ClassCastException.
Testcase: SpringDefectInQueryMapperTest
spring-boot version 3.0.11 spring-data-mongodb version 4.0.10
Exception:
java.lang.ClassCastException: class org.bson.Document cannot be cast to class java.time.LocalDate (org.bson.Document is in unnamed module of loader 'app'; java.time.LocalDate is in module java.base of loader 'bootstrap')
