          Issue ID: 125355
        Issue Type: DEFECT
           Summary: Checking for too many Accessible children in parallel
                    seems to bring the accessibility api in a dead lock
           Product: App Dev
           Version: 4.1.0
          Hardware: PC
                OS: Windows 7
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: api
          Assignee: issues@openoffice.apache.org
          Reporter: jens.bornschein@tu-dresden.de

When I'm checking all accessible child elements (XAccessible) of an
XAccessibleContext (var c = haystack.getAccessibleChild(i);) via the cli api
from C# the api seems to fall into some kind of dead lock. The OpenOffice
process stops and doesn't response for any user interaction. When I abort my
requesting application OpenOffice runs normally from this point.

I'm checking every available XShape on an XDrawPage for its XAccessible
counterpart in parallel, starting the search from the base XAccessible which I
have received from the XDrawPagesObservers Model ComponentWindow. Testing all
elements serial will take too much time. The time until it hangs on isn't every
time the same. I don't found any rule when it starts hanging.

In my testes I have a draw doc width circa 30 objects, building (incl. bézier
curves for text) nearly 100 objects in the navigation tree.
