[JAVA] Client can't deserialize date-time

Description

I'm generating a Java client from my swagger definition created from my ASP .Net Core backend. When I call my Java client API to downloading a list of objects I get an exception as it fails to deserialize a field that is a date-time. This works for my generated TypeScript client but not for the Java client.

Start by reproducing the issue with the listed swagger-codegen command and Swagger declaration. Compare the downloaded data and exception from the linked gists with the generated Android/Volley client’s date-time handling. Done means the generated Java client can deserialize the date-time field when downloading the object list.
