Does the vtk java version support SMP?

Does the vtk java version support SMP?
I compiled vtk9.3 under windows, JDK1.8, set the parameters and turned on
VTK_WRAP_JAVA
VTK_SMP_ENABLE_OPENMP
VTK_SMP_ENABLE_SEQUENTIAL
VTK_SMP_ENABLE_STDTHREAD
VTK_SMP_IMPLEMENTATION_TYPE STDThread
VTK_MODULE_ENABLE_VTK_FiltersMP YES

in test code
public SimpleVTK() {
super(new BorderLayout());

 // compile error
 vtkSMPTools smpTools = new vtkSMPTools();
 smpTools.SetBackend("STDThread");

 //.......

}

The IDE error message: ‘vtk.vtkSMPTools’ is not public in ‘vtk’. Cannot be accessed from outside package.
It seems vtkSMPTools can not be used in vtk java.
Do I missed something or just SMP not supported in vtk java?

Notice:
I have run vtk java program normally without using vtkSMPTools.

Thanks!

I suspect that VTK’s Java wrapper generators can’t wrap these classes effectively. @dgobbi?
