Okay, I'll try this again. You guys are my only hope.
It appears that the class loader or JVM is crashing on me with a
segmentation violation. This sounds like a MAJOR bug in the JVM.
However, I have found no references to anything like it anywhere in the
newsgroups. Does anyone have any information on a bug that would
produce the error listed below?
Thanks!
