Proof step 5 from proof exactarray-out (previous step)

jvmref -- mkfs(`java.lang.Object' .class, void_type, `out' .field) ' = val .refval -- sk ⊦ exactarray(val, ty, i, st[jvmref -- mkfs(`java.lang.Object' .class, void_type, `out' .field) ', val0]) ↔ exactarray(val, ty, i, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ r -- sk = r0 -- sk0 ↔ r = r0 ∧ sk = sk0
Proof step 4:
⊦ val .refval = jvmref → ¬ exactarray(val, ty, i, st)

Rule argument

[speclemmaarg: ,r -- sk = r0 -- sk0 ↔ r = r0 ∧ sk = sk0 ,[sk0, r0, sk, r] → [sk, val .refval, mkfs(`java.lang.Object' .class, void_type, `out' .field) ', jvmref] ,F ,refkey , ,inj ]
