Undergrad: Allen Hatcher's recommendation got me into Cornell (I learned Algebraic Topology through his book in high school, along with some email correspondences). But I majored in Engineering Physics and did experimental research on gravity.
Grad: I started my PhD in experimental atomic physics at Berkeley, but quit to do math. I am now a student of Michael Hutchings!

Classes in $H^3(G; \mathbb{Z})$ that restrict to zero on abelian subgroups
I wrote up computations for all pgroups which contain an indexp cyclic subgroup; it's on my website. Perhaps you can use them (pass from $\mathbb{Z}_p$coefficients to $\mathbb{Z}$ via Bockstein) to find your desired integral elements (they'll have to come from degree 2 elements in modp cohomology for the generalized quaternions or splitmetacyclic groups). Anyway, now that you're here at Berkeley with me, we can meet sometime and chat further! (and recruit Qiaochu to use his secret category theory powers)

What motivates this question?

@MatthiasWendt, unfortunately that's only for modp cohomology. But perhaps the Bockstein homomorphism is nontrivial in this case, which will produce essential elements with $\mathbb{Z}$coefficients.

Note that I'm cheating with the example I gave, because $H^\text{odd}$ is zero for cyclic groups.

Reference Request: “Neck Stretching Procedure” (In Symplectic Field Theory)
It's on page 13, around Definition 1.6.1.

Is the Nijenhuis tensor an obstruction to the existence of non constant pseudoholomorphic maps?
Ah I am implicitly fixing the target $(M,J_M)$. I speak of generic $(N,J_N)$ which is consistent with your observation.
