Proof step 15 from proof ac-del-01 (previous step)

fs = mkfs(class, ty, fieldvar), ∀ class1, sk, val0, st, val. (addclass(class1, fis0 + (sk × val0) ', st)[jvmref -- sk, val]) = (addclass(class1, fis0, st)[jvmref -- sk, val]) ⊦ (addclass(class, ((fs ' × val1) ' + fis0) + (sk × val0) ', st)[jvmref -- sk, val]) = (addclass(class, (fs ' × val1) ' + fis0, st)[jvmref -- sk, val])

And obtained the following new goals

Proof step 5:
⊦ addclass(class1, (mkfs(class1, ty, fieldvar) ' × val) ' + fis, st) = (addclass(class1, fis, st)[jvmref -- mkfs(class1, ty, fieldvar) ', val])
Proof step 14:
∀ class1, sk, val0, st, val. (addclass(class1, fis0 + (sk × val0) ', st)[jvmref -- sk, val]) = (addclass(class1, fis0, st)[jvmref -- sk, val]) ⊦ (addclass(class, fis0 + (sk × val0) ', st)[jvmref -- mkfs(class, ty, fieldvar) ', val1][jvmref -- sk, val]) = (addclass(class, fis0, st)[jvmref -- mkfs(class, ty, fieldvar) ', val1][jvmref -- sk, val])
