I take it that the GDB stack trace did not help.
Steve got the latest fixes and swarm.jar and is now getting the same error
that I got on both my machines:
...

I tried running jdb in bash, but it didn't get very far.

address@hidden//c/SwarmSyncer/FlintstoneMM/FredAndWilma] $ jdb -classpath
$CLASSPATH TestMapIndexOld
java.lang.ClassNotFoundException: sun/tools/ttydebug/TTY

In DOS, two of us can't get jbd to work any more either:
C:\SwarmSyncer\FlintstoneMM\FredAndWilma>javac -g TestMapIndexOld.java

We have 5 machines among 4 swarm programmers, and for all of them, the
simple example breaks at the second-to-the-last line (that calls index.next
on the time unit that contains the two actions).

BTW, schedule.xfprint() works fine and indicates to me (after looking at the
source code Schedule.m) that maybe in ObjectiveC the key is cast from an
'int' to be an 'id' (a pointer).  Maybe this is working fine when
manipulating the schedule from inside the objective C library routines, but
perhaps this is causing problems when trying to pull the individual entries
back out into java. This would explain the really wierd stack trace, since
integers are being read as pointers. But that doesn't explain why it works
for you, and not for us.  

Here is the output from a machine on which we were able to get jbd to work:

Thanks for any help you can give.
