Proof step 25 from proof okarray-put-samefield-01 (previous step)

fs = mkfs(class, ty0, fieldvar), r ∈ st, okval(val, ty0), okval(st[r -- fs '], ty0), r -- fs ' ∈ st, okarray(r, ty, st[r -- fs ', val]) ⊦ r = jvmref, fs ' = _type, fs ' = _length, okarray(r, ty, st)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 4:
⊦ okarray(r, ty, st) → r ≠ jvmref ∧ r ∈ st
Proof step 24:
okarray(r, ty, st[r -- mkfs(class, ty0, fieldvar) ', val]), r -- mkfs(class, ty0, fieldvar) ' ∈ st, okval(st[r -- mkfs(class, ty0, fieldvar) '], ty0), okval(val, ty0), r ∈ st ⊦ mkfs(class, ty0, fieldvar) ' = _length, mkfs(class, ty0, fieldvar) ' = _type, r = jvmref, okarray(r, ty, st)
