[vtkusers] crash: EXCEPTION_ACCESS_VIOLATION error in native code outside th e Java VM

Sorry.

I forgot to mention that I am using VTK 4.0 and JDK 1.4.0 on Windows 2000. 
Thanks, John.

Hi Lichan,

it looks like you have a problem but noone will be able to help you unless 
you give more info.

at least tell people what version of VTK you are using.

It would also be nice to know what OS and what Java you are using, although 
the problem does look like it is in VTK code, not java or OS code. 

good luck!

john
