Parallel Problem in Activiz

Development
1

i am using the activiz 9.4, and i want to use a Parallel.For to create multi vtkCell in the same time,the code like this :

        Parallel.For(0, input.GetNumberOfCells(), i =>
        {
            var temp = vtkCell.New();
        });

input is a vtkPolyData, it throw a “error: IndexedConstructors table already has a non-null entry at mteIndex 18”. But if i use vtkPolyData:

        Parallel.For(0, input.GetNumberOfCells(), i =>
        {
            var temp = vtkPolyData.New();
        });

it works. Is it a bug or a feature?

Both Activiz and VTK are not thread safe. This issue was discussed in this thread: GetConstructorInfo exception on multiple thread.
We have a partial solution to improve this, please reach out to me directly if you want to discuss how we could work together to add this to the next Activiz release.
