RE: error

[Fred Wan]

The error occurs in main directly after initialization of the swarm

Globals.env.initSwarm(...)

and it happens in all the swarm projects I have written and tried to run
(which are a lot), including in older versions as well as on the swarm
examples provided on the swarm download site, none of which use conformsTo.
Also the line

*** function: nil_method(), file:  /src/Swarm/swarm/src/defobj/internal.m,

suggests that it happens sowhere in the swarm code itself...
