I see the same anomaly for the "i.7" argument on J 9.02.03 under Windows 10:
test1=: 0:`1:`2: @. (3&|)
test1 &.> i.&.> >:i.6
+-+---+-----+-------+---------+-----------+
|0|0 1|0 1 2|0 1 2 0|0 1 2 0 1|0 1 2 0 1 2|
+-+---+-----+-------+---------+-----------+
test1 i.7
|rank error: test1
|test1[0]
dbr 1 [ dbr 0
test1 i.100
|rank error: test1
|test1[0]
But defining "test1" with scalar rank does not exhibit this behavior:
test1=: 0:`1:`2: @. (3&|)"0
test1&.>i.&.>7+i.3
+-------------+---------------+-----------------+
|0 1 2 0 1 2 0|0 1 2 0 1 2 0 1|0 1 2 0 1 2 0 1 2|
+-------------+---------------+-----------------+
