Shame on me.
Please excuse me. I'm stupid, i say "exactly the same method" , but
not really...
My own error is here :
...
fi = fc.features();
...
fi = fc.features();
...
Two call fc.feature() so two iterator opening !!
As always the problem, it is what there is between the chair and the
keyboard
Thanks for your help.
