Let algebras be Artin algebras. It is well known that a an algebra has global dimension at most one if and only if the Jacobson radical is projective. As reflexive is a natural generalisation of projective, one might ask when the Jacobson radical $J$ is reflexive. I noted that for Nakayama algebras one has that $J$ is reflexive if and only if the finitistic dimension is at most one. But in general such a statement would probably be too good to be true.

Question: Is there an easy counterexample to $J$ being reflexive implies finitistic dimension at most 1?

(the other direction is not true, see answer below)

Reflexive means that the canonical evaluation map $f_M:M \rightarrow M^{**}$ is an isomorphism where for an algebra $A$: $M^{**}=Hom_A(Hom_A(M,A),A)$. Here $f_M(m)=g$ with $g(h)=h(m)$.
