Hi,
Sorry, I thought maybe you see directly a fault in my code.
Here is (a complete new) code now, where the failure still exists. If you start
the program, you will directly see the problem. I hope the code is clear enough.

Sorry, can't use the above.
I will be pleased to have a look if, as said before, you provide
me with "a data set and a little self
contained program that shows the behaviour you deem to be unsatisfactory".
That means a full runnable java file with a main that will
draw a map showing the issue along with the data set
that makes the problem occur.
I don't have time to replicate the issue by myself.
Cheers
Andrea
