It is in the core engine.

The code that does the differencing is in the package:
org.crosswire.common.diff
This is a java implementation of some open source javascript code that I 
found.

The code that uses it to is in the class:
org.crosswire.jsword.book.BookData.java

And there is a helper to convert the diff list into OSIS in:
org.crosswire.jsword.book.OSISutil.diffToOsis()

Here is a snippet on how it is used:
    // Compare the text of two verses, excluding OSIS or other markup
    List diffs = new Diff(lastText, thisText, false).compare();
    // Make the diff more meaningful
    DiffCleanup.cleanupSemantic(diffs);
    // Convert it to osis
    String osisFragment = OSISUtil.diffToOsis(diffs);
