vtk java voxel rendering -
hi guys,
does knows, why code in java compiles, error appears:

the message
the crash happened outside java virtual machine in native code.
should give indication error happening outside of java looking @ java code of little help.
the typical cause of stack overflow (regardless of language) recursive call never reaches base case , hence never starts tracking. reason each call method causes return address (reference) placed on stack, more calls made more return addresses stored until there no more space on stack.
did quick google happening in vtkvolumerendering.dll @ other times , found if it's help.
link here in case above didn't work :)
