    I modified the code to throw an Error and then ran the SplitIT.
    
    Below is what the stack trace looks like when I just cast the error.
    ```
    java.lang.NoSuchMethodError

    below is what the stack trace looks like when I wrap the Error... .this has the important
info that AddSplitIT.java line 62 called addSplits()
