I don't know what version of Jess you're using here, but the current
production version (7.0p2) says
Jess reported an error in routine Group.add.
Message: CE can't be used in logical: test.
While the current development version (7.1b1) accepts this and
executes it correctly. Support for "test" inside of "logical" is a
new feature.

Whenever I use "test" inside a "logical" Rule on the LHS, I get the
exception
error:
Unexpected exception:
jess.NodeJoin cannot be cast to jess.Node2
How can I avoid this?
(ie)
(defrule xyz
(logical
..
...
(test (< ?dt_x ?y))
);; Logical
=>
(
