A DESCRIPTION OF THE REQUEST :
BasicListUI defines some actions to deal with cursor movements in JList. When the layout orientation is set to JList.HORIZONTAL_WRAP the list does not wrap to the previous (next) line if the left (right) cursor key is pressed when the left (right) most item is selected.

The crucial code is in BasicListUI getNextColumnIndex. if the check for the new column index fails -1 is return with the comment: //no wrapping.

Please make wrapping at least optional possible.

JUSTIFICATION :
It makes 'walk through items' in multi column lists much easier, especially if the elements are sorted in the list.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
I would like the selection to wrap to the next/previous row, if the end/begin of the current row is reached.
ACTUAL -
The list stays on the first/last item of the current row.
