[vtkusers] vtk (java version) heap memory problem: EXCEPTION_ACCESS_VIOLATION

I have a large dataset that I am trying to visualize
using vtk contouring filter from java.
I am only able to visualize about 60 % of the dataset.
This works fine. But if I try to visualize more I get
the following error:

An unexpected exception has been detected in native
code outside the VM.
Unexpected Signal : EXCEPTION_ACCESS_VIOLATION
occurred at PC=0x77F83AED
Function=RtlSizeHeap+0x7D7
Library=C:\Windows\System32\ntdll.dll

Current Java thread:
	at vtk.vtkRenderWindowInteractor.Start_5(Native
Method)
	at
vtk.vtkRenderWindowInteractor.Start(vtkRenderWindowInteractor.java:32)
	at
com.interaction.avt.j3d.filters.iaTestFilter.<init>(iaTestFilter.java:299)
	at
com.interaction.avt.j3d.filters.iaTestFilter.main(iaTestFilter.java:390)

Dynamic libraries:
0x00400000 - 0x00407000 
C:\j2sdk1.4.1_02\bin\javaw.exe
0x77F50000 - 0x77FF7000 	C:\Windows\System32\ntdll.dll
0x77E60000 - 0x77F46000 
C:\Windows\system32\kernel32.dll

Is there a way to increase the heap memory size or is
this caused by something else?

Here is part of my java code:

 vtkPolyData polydata is created based on my dataset;

 vtkContourFilter filter = new vtkContourFilter();
 filter.SetInput(polydata); 
 filter.GenerateValues(10, mini, maxi);
      
 vtkPolyData pd = filter.GetOutput();
  
 pd.Update(); // Here it crashes if more that 60 % of
the dataset is used.


Thanks in advance :-)

Best regards
