Did you miss my comment up thread "Having some fun , online , with a good p. It’s a good time to test the 1nt waters." ?

It would be legal in FIGB, even with a 2 instead of J.
The interesting (and not very logical) limitation is that it has to be in range to include a singleton. Which might be interpreted to mean that upgrading this hand to 1D as worth 18 would be illegal if you have the agreement to open it 1NT in range 15-17.
