Proof step 9 from proof validrefkeynotnull-statfield-intersect (previous step)

st[jvmref -- fs '] = refval(r), st .refs ∩ st1 .refs = ∅, jvmref ∈ st, jvmref ∈ st1, validrefnotnull(str, r, ty, st), is_referencevalue(st[jvmref -- fs ']), jvmref -- fs ' ∈ st ⊦

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 8:
st .refs ∩ st1 .refs = ∅, st[jvmref -- fs '] = refval(r), jvmref -- fs ' ∈ st, validrefnotnull(str, r, ty, st), jvmref ∈ st1, jvmref ∈ st ⊦
