Proof step 19 from proof validstatfield-addclass-same (previous step)

fs = mkfs(class, ty, fieldvar), validval(str, fis[fs '], ty, st), fs ' ∈ statfields(class), tdname∃(str, class), type∃(str, ty), fs ' ∈ fis ⊦ class = `java.lang.Object' .class, validstatfield(str, fs ', addclass(class, fis, st))

And obtained the following new goals

Proof step 18:
validval(str, fis[mkfs(class, ty, fieldvar) '], ty, st), mkfs(class, ty, fieldvar) ' ∈ statfields(class), tdname∃(str, class), type∃(str, ty), mkfs(class, ty, fieldvar) ' ∈ fis ⊦ class = `java.lang.Object' .class, validstatfield(str, mkfs(class, ty, fieldvar) ', addclass(class, fis, st))
