Extension of holomorphic vector bundles across a boundary point

Let U ? C ⁿ , n ≥ 3, be a domain and P ∈ ?U such that U is 2-concave at P. Here we prove the existence of a holomorphic vector bundle on U which does not extend across P, but it extends across every Q ∈ ?U with Q ≠ P. We also prove a similar result taking a Stein space X instead of C ⁿ .
