MapContent.LayerList.set(int, Layer) method is not safe
-------------------------------------------------------
Key: GEOT-3918
URL: https://jira.codehaus.org/browse/GEOT-3918
Project: GeoTools
Issue Type: Bug
Components: render
Affects Versions: 8.0-M2, 2.7.3
Reporter: Michael Bedward
Assignee: Michael Bedward
Fix For: 2.7.4, 8.0-M3
In version 8, the MapContent.LayerList.set(int, Layer) method replaces the
element at the specified list position with the given layer and then fires a
"layer moved" event. The method thus effectively allows a layer to be removed
and another added while by-passing the usual events associated with these
operations. Unless there is an obvious need for this method it should be
changed to throw an UnsupportedOperationException.
(In version 2.7.x the same issue applies in the anonymous list class returned
by the MapContent.layers() method)
