java.lang.IllegalArgumentException: wrong number of arguments while serializing LocalDateTime object.

[slaaridh]

Hello,

I have the following stacktrace when I tried to serialize a LocalDateTime object. It seems that genson consider the "LocalDateTime .isAfter" method as an accessor, however this is not the case.

Hi @slaaridh , by default Genson doesn't know how to treat these types so it's considering them the same as classic java beans. For java.time types to be correctly supported you can take a look at this https://github.com/owlike/genson/tree/master/genson-java-datetime.
