mkfs(class0, ty, fieldvar) ' ≠ mkfs(class0, ty0, fieldvar0) ', ∀ class, st, ty, fieldvar, val.

And obtained the following new goals

Proof step 8:
⊦ addclass(class1, (mkfs(class1, ty, fieldvar) ' × val) ' + fis, st) = (addclass(class1, fis, st)[jvmref -- mkfs(class1, ty, fieldvar) ', val])
Proof step 12:
∀ class, st, ty, fieldvar, val. (addclass(class, fis0, st)[jvmref -- mkfs(class, ty, fieldvar) ', val]) = addclass(class, fis0[mkfs(class, ty, fieldvar) ', val], st), ty ≠ ty0 ∨ fieldvar ≠ fieldvar0 ⊦ (addclass(class0, fis0, st)[jvmref -- mkfs(class0, ty0, fieldvar0) ', val0][jvmref -- mkfs(class0, ty, fieldvar) ', val]) = (addclass(class0, fis0[mkfs(class0, ty, fieldvar) ', val], st)[jvmref -- mkfs(class0, ty0, fieldvar0) ', val0])
