Proof step 3 from proof in-put-keys-01 (previous step)

str ≠ `java.lang.Object' ⊦ r0 -- _type ∈ st[r -- (sks + mkfs(str .class, ty, fieldvar) ' '), val] ↔ r0 -- _type ∈ st

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 2:
⊦ str = `java.lang.Object', r0 -- _type ∈ st[r -- (sks + mkfs(str .class, ty, fieldvar) ' '), val] ↔ r0 -- _type ∈ st
