[jira] Commented: (HARMONY-2643) [classlib][swing]
j.s.undo.UndoManager.setLimit throws ArrayIndexOutOfBoundsException
[ http://issues.apache.org/jira/browse/HARMONY-2643?page=comments#action_12457701 ]
Alexey A. Ivanov commented on HARMONY-2643:
-------------------------------------------
Despite that the negative setting for limit is kept, it seems to not have any effect to object behavior: you can still add UndoableEdits to it, and they will be undone as if the limit was not changed. It might be a bug of RI. (Setting limit to 0, prevents you from adding edits to UndoManager.)
