will this work with the custom-type adapter? in the existing example, it's parsing by using the nested gson instance where we register the adapters?

    Object obj2 = client
            .getJSON()

Hrm, I think that Gson adapters are injected via annotation so that they would work everywhere, e.g. https://github.com/kubernetes-client/java/blob/master/kubernetes/src/main/java/io/kubernetes/client/custom/Quantity.java#L14

java/kubernetes/src/main/java/io/kubernetes/client/JSON.java

Lines 46 to 54 in 607a34b

public JSON() {
gson = new GsonBuilder()
.registerTypeAdapter(Date.class, dateTypeAdapter)
.registerTypeAdapter(java.sql.Date.class, sqlDateTypeAdapter)
.registerTypeAdapter(DateTime.class, dateTimeTypeAdapter)
.registerTypeAdapter(LocalDate.class, localDateTypeAdapter)
.registerTypeAdapter(byte[].class, byteArrayTypeAdapter)
.create();
}

but here we're registering the adapters explicitly

Ah, that's true for those built-ins we can't annotate...


System.out.println(returnData);
