I'm running Kaffe 1.0.7 on OpenBSD 3.1 (i386).  I'm using it to run
Freenet.  My Freenet node was running along happily for a few days,
then it crashed this morning, with this message:

assertion "FD_ISSET(i, &readsPending)" failed: file "jthread.c", line 1748

It left a core file behind, with the following stack trace:

The actual command in my node's start script is:
