    Description

      NOTE: This suggestion is for JIRA Server. Using JIRA Cloud? See the corresponding suggestion.

      In ChartHelper we call

      ServletUtilities.saveChartAsPNG(chart, width, height, renderingInfo, null);

      That "null" tells jfreechart to generate a "one-time" image. As soon as jfreechart has sent it out to someone it deletes it. This causes problems in IE6 which seems to have a bug where it sometimes requests the same image twice in a row. This results in the second request getting a 404 (since jfreechart already deleted it).

      jfreechart also supports "per-session" images. We just need to pass in the HttpSession instead of null and jfreechart will keep the image around for the session.

      Andreas thinks this change was supposed to have happened in 4.0.x but it appears to have fallen through the cracks. We should put it into 4.1.x
