User applied rule structural induction

And obtained the following new goals

Proof step 15:
r2 ∈ st0, 0 < i3, 0 ≤ i, 0 ≤ i2, exactarray(r2, int_type, st0), i < i3, i2 + i3 ≤ st0[r2 -- _length] .intval ⊦ r2 = jvmref, r1 = r2, (r -- sk ∈ arraycopy(r1, i1, r2, i2, i3, st0[r2 -- (i2 + i) ', val]) ↔ r -- sk ∈ arraycopy(r1, i1, r2, i2, i3, st0)) ∧ (arraycopy(r1, i1, r2, i2, i3, st0[r2 -- (i2 + i) ', val])[r -- sk]) = (arraycopy(r1, i1, r2, i2, i3, st0)[r -- sk])
