This seems to be the "root error" on the console.
However, that line is monitor.serviceException. The
actual exception it is trying to service when I step
thru in the debugger is the hivemind error I was
talking about in the previous email.
If you don't have any better ideas, I'll try with a
clean slate and introduce Trails a piece at a time
until I see what is causing it to break. This was my
attempt to upgrade an existing Trails example to 4.0.
getRootCause():
java.lang.NullPointerException
