MapView crashes while rendering random geometries

[MathiasBecher]

Some time ago, I asked this question on Stackoverflow. Sadly, I didn't get an answer yet.

For convenience, I provide the text of the question here again (better formatting on Stackoverflow). Hopefully, someone can help me.

I am using the Esri ArcGISRuntime for WPF SDK.

When I add a specific geometry to a graphics layer the runtime throws an exception:

System.Exception was unhandled HResult=-2146233088 Message=Geometry is corrupted and can not be used. : Source=Esri.ArcGISRuntime StackTrace: at RuntimeCoreNet.Interop.HandleException(Boolean retVal) in Interop.cs: line 54 at RuntimeCoreNet.CoreGeometryEngine.ProjectForDisplay(ICoreGeometry[] coreGeometries, CoreSpatialReference[] inCoreSRs, CoreSpatialReference outCoreSR) in CoreGeometryEngine.cs: line 77 at RuntimeCoreNet.CoreGraphicsLayerWrapper.ReprojectGeoms(ICoreGeometry[] geomArray, CoreSpatialReference[] inSRArray, CoreSpatialReference outSR, List`1 reprojectionIndicies) in C:\Users\mathias.becher.INTRANET\AppData\Local\JetBrains\Shared\v01\DecompilerCache\decompiler\207C5F0B-5A6C-43F9-AA7E-BA622D21C04A\71\43e7a7ec\CoreGraphicsLayerWrapper.cs: line 58 at RuntimeCoreNet.CoreGraphicsLayerWrapper.AddGraphicsInternal(AdditionInfo additions, SpatialReference mapSR) in C:\Users\mathias.becher.INTRANET\AppData\Local\JetBrains\Shared\v01\DecompilerCache\decompiler\207C5F0B-5A6C-43F9-AA7E-BA622D21C04A\71\43e7a7ec\CoreGraphicsLayerWrapper.cs: line 196 at RuntimeCoreNet.CoreGraphicsLayerWrapper.UpdatePendingGraphics() in C:\Users\mathias.becher.INTRANET\AppData\Local\JetBrains\Shared\v01\DecompilerCache\decompiler\207C5F0B-5A6C-43F9-AA7E-BA622D21C04A\71\43e7a7ec\CoreGraphicsLayerWrapper.cs: line 269 at Esri.ArcGISRuntime.Controls.ViewBase.MapBatchProcess() in C:\Users\mathias.becher.INTRANET\AppData\Local\JetBrains\Shared\v01\DecompilerCache\decompiler\207C5F0B-5A6C-43F9-AA7E-BA622D21C04A\09\765599cd\ViewBase.cs: line 1474 at Esri.ArcGISRuntime.Controls.ViewBase._batchUpdateTimer_Tick(Object sender, Object e) in C:\Users\mathias.becher.INTRANET\AppData\Local\JetBrains\Shared\v01\DecompilerCache\decompiler\207C5F0B-5A6C-43F9-AA7E-BA622D21C04A\09\765599cd\ViewBase.cs: line 1463 at System.Windows.Threading.DispatcherTimer.FireTick(Object unused) at System.Windows.Threading.ExceptionWrapper.InternalRealCall(Delegate callback, Object args, Int32 numArgs) at MS.Internal.Threading.ExceptionFilterHelper.TryCatchWhen(Object source, Delegate method, Object args, Int32 numArgs, Delegate catchHandler) at System.Windows.Threading.DispatcherOperation.InvokeImpl() at System.Threading.ExecutionContext.RunInternal(ExecutionContext executionContext, ContextCallback callback, Object state, Boolean preserveSyncCtx) at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state, Boolean preserveSyncCtx) at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state) at System.Windows.Threading.DispatcherOperation.Invoke() at System.Windows.Threading.Dispatcher.ProcessQueue() at System.Windows.Threading.Dispatcher.WndProcHook(IntPtr hwnd, Int32 msg, IntPtr wParam, IntPtr lParam, ref Boolean handled) at MS.Win32.HwndWrapper.WndProc(IntPtr hwnd, Int32 msg, IntPtr wParam, IntPtr lParam, ref Boolean handled) at MS.Win32.HwndSubclass.DispatcherCallbackOperation(Object o) at System.Windows.Threading.ExceptionWrapper.InternalRealCall(Delegate callback, Object args, Int32 numArgs) at MS.Internal.Threading.ExceptionFilterHelper.TryCatchWhen(Object source, Delegate method, Object args, Int32 numArgs, Delegate catchHandler) at System.Windows.Threading.Dispatcher.LegacyInvokeImpl(DispatcherPriority priority, TimeSpan timeout, Delegate method, Object args, Int32 numArgs) at MS.Win32.HwndSubclass.SubclassWndProc(IntPtr hwnd, Int32 msg, IntPtr wParam, IntPtr lParam) at MS.Win32.UnsafeNativeMethods.DispatchMessage(ref MSG msg) at System.Windows.Threading.Dispatcher.PushFrameImpl(DispatcherFrame frame) at System.Windows.Application.RunInternal(Window window) at System.Windows.Application.Run()

The message is sometimes

Geometry is corrupted and can not be used. :

and sometimes

Out of Range :

The ArcGIS JSON for the Geometry looks like this:

Does anybody know what the problem is with this geometry? Is this a bug with the ArcGIS runtime, or do I need to take some special care when creating geometries? (This specific geometry is the result of Unioning multiple smaller geometries using GeoAPI.)

[MathiasBecher]

After further investigation, the problem seems to happen, when there are very small multipart geometry parts. The above geometry for example, contains a part with an area of about 0.6m².

But in my opinion the runtime should definitely not crash on encountering such a geometry.
