Bug 355679

Description Robert Brodt 2011-08-24 06:42:34 EDT

This happens when the number of "ad hoc" anchors is > 1.
In AnchorUtil#deleteEmptyAdHocAnchors() just reverse the lower and upper bounds in the first "for" like so:

Was:
for (int i = 0; i < s.getAnchors().size(); i++)

Should be:
for (int i = s.getAnchors().size()-1; i >= 0; --i)

Stack trace follows:
