I am using the FreeBSD native JDK 1.2.2 pl 10 (compiled against OpenMotif).
I have a java program that downloads stock data from the Internet and it is
run nightly as a cron job. Anyway, from time to time, it aborts with a core
dump. This appears to be a JDK problem and not a code problem.
Unfortunately, I have lost the original source code (because of a Windows
2000 drive reformat) when I forgot to back it up. I do have the jar though.
I get the following error.
