Michael McCandless commented on TIKA-1033:
------------------------------------------
Interesting: with PowerPoint 2007, when I double-click the embedded chart, it
pops up a dialogue box saying "To edit this chart using the new features
available in the 2007 Microsoft Office system, you must first convert it to the
2007 Office system format. Do you want to convert this chart to the new
format? [Convert] [Convert All] [Edit Existing]". If I click [Edit Existing]
it lets me edit the chart data in what looks like Excel, in "Compatibility
Mode".
OK I'll open a POI bug and reference back to this issue...
Thanks Nick.

> I have an example ppt that embeds a chart, but Tika mis-identifies it

> The progID (oleShape.getProgID() in

> Since DelegatingParser silently suppresses all exceptions, when you

> TikaCLI hits the above exception.
