DJ supports the very useful feature that you can maintain

to get rid of the unwanted tail edges in the class graph.

You may want to use this feature in your project later
to solve the problem once and for all.

the workaround for an example in:

If you want to use this feature of DJ, you need to follow the
workaround instructions.

Notice how the oo features help to deal with such bug fixes.
