[jira] [Updated] (JOHNZON-219) A null classMapping for inner class
with fields.
[ https://issues.apache.org/jira/browse/JOHNZON-219?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jin Kwon updated JOHNZON-219:
-----------------------------
Description:
I'm sorry I can't find any good words for the issue.
With following code,
{code:java}
public static class Some<T, U extends Some.SomeError<?>, V> {
public static class SomeError<W> {
@Setter
@Getter
private int code;
@Setter
@Getter
private W data;
}
@Setter
@Getter
private T t;
@Setter
@Getter
private U u;
@Setter
@Getter
private V v;
}
public static class VoidSome extends Some<Void, Some.SomeError<Void>, Void> {
}
@Test
void test() throws IOException {
final String a = "{\"t\": null, \"u\": {\"code\":1}, \"v\": null}";
final String b = "{\"t\": null, \"u\": null, \"v\": null}";
//final Some<Void, Some.SomeError<Void>, Void> value = JSONB.fromJson(b, VoidSome.class);
final Some<Void, Some.SomeError<Void>, Void> value = JSONB.fromJson(a, VoidSome.class);
log.debug("value: {}", value);
}
{code}
I got,
{code}

Weird somehow,
When I remove {{code}} property and use {{b}} instead, it works.
I tried to debug the code and I failed.
