It beats me. Some more options: 1) Try to run it from an IDE with a nice debugger 2) Get the CVS version and insert more log statements 3) Try a different driver if you can 4) Try a different JDK if you can
There is no System.exit() in my code. Maybe some fishy JNI stuff in the IBM driver kills the VM? You know, JDBC drivers are *always* buggy in the meta data parts. -At least all the ones I have tried.
