As a fault localization tool, your objective is to identify potential buggy lines within a specific method. The bug was triggered by the test case "org.joda.time.TestPartial_Constructors::testConstructorEx7_TypeArray_intArray" and resulted in the following error message: "junit.framework.AssertionFailedError".
Based on the provided context, please provide a concise and precise response containing the potential buggy lines in the following format: (line number: source code).
To assist you in debugging, the methods that requires attention are:
