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.jfree.data.time.junit.TimePeriodValuesTests::testGetMaxMiddleIndex" and resulted in the following error message: "junit.framework.AssertionFailedError: expected:<1> but was:<3>".
To assist you in debugging, the methods that requires attention are:
// Method 0 
1 public int getMaxMiddleIndex() {
2         return this.maxMiddleIndex;
3     }
// Method 1
