Well, that should work. Here are the results I get with Jacl 1.3
from the CVS.

$ make shell
% set res [catch {exec false} s]
1
% set res
1
% set s
child process exited abnormally
% set res [catch {exec echo hi} s]
0
% set s
hi

Perhaps the fact that you left the catch out is raising
a TclException and your Java code fails to catch it.
