This was a problem with java. However a patch has been applied. Get
vtkJavaAwt.h revision 1.19 or later and build vtk.

> I'm  using vtkPanel in my java application.
> Recently I discovered that this class was extensively consuming GDI
> objects.
> After some time the max limit of GDI objects was reached and my PC
started

>
> I'm using WIN2000, but the same thing happened on XP.

> Is this a bug in the vtk C code ?
> Can someone else verify this behavior by running
> vtk42\Wrapping\Java\TestVTKCanvas.java ?
> GDI consumption can be monitored with Windows Task Manager
>
> What GDI is :
> The graphical component of the Microsoft Windows graphical environment
is
> the graphics device interface (GDI).
> It communicates between the application and the device driver, which
> performs the hardware-specific functions that generate output.
> By acting as a buffer between applications and output devices, GDI
> presents
> a device-independent view of the world for the
> application while interacting in a device-dependent format with the
> device.
