I think it is a general problem.  I ran all the tests and got, if I
remember correctly, 12 PASSES and 4 FAILS.  I ran the tests on my fast
computer at work, but now I am at home and can't remember exactly.

The reason I didn't have any second thoughts about reducing them all
is because the rest of the EJ patterns after EJ4 were all j patterns
instead of J.
