Absolutely. I was trying to convince people here to use vtk (+itk) for
some development the other day and the (java) app died in mid demo
because some obscure exception happened deep inside vtk. Normally I wrap
all render calls in try catch blocks when doing C++ development, but
with wrapped languages its less convenient.
