Thank you for the quick response. I just spent the last eight hours using my application and the Segmentation Fault didn't happen again. I didn't have the -Dprism.verbose=true set during the run. I also didn't find a hs_err*.log from this morning's crash. I can turn on verbose tomorrow morning and see if it happens again.
