Description
I noticed this issue when updating my lambda function from Java 8 to Java 11, and it seems to be related to the code in this repository.
The problematic situation occurs when a lambda function declares that it returns TestParent
, but actually returns an instance of TestChild
:
public class TestParent {
public String parentField = "parentField";
}
public class TestChild extends TestParent {
public String childField = "childField";
}
To reproduce the issue, please run the attached test case (maven project): aws-lambda-json-child-field-bug.zip
It should fail with an error like below:
org.junit.ComparisonFailure:
Expected :{"parentField":"parentField","childField":"childField"}
Actual :{"parentField":"parentField"}
You can see that the fields from TestChild
are missing. This is the issue, and this seems to be new -- in the Java 8 lambda runtime this worked ok.
Thanks for any help!
