The `read()` method now catches `ClassCastException` for the outer deserialization, but `apply()` has no guard here. ```suggestion if (!(o instanceof JsonObject rule)) { continue; } JsonObject expectation = (JsonObject) rule.get("expectation"); ``` -- This is an automated message from the Apache Git Service.
