And obtained the following new goals

Proof step 152:
st[r -- _length] = intval(i), st[r -- _type] = typeval(mkarraytype(ty0)), fis .keys = statfields(class), 0 < i, 0 ≤ j, 0 ≤ i, j < i, compatmode(str, st), compatstatic(str, st), okfieldinits(class, fis), r -- _type ∈ st, r ∈ st, is_arrayref(r, i, st), is_integervalue(st[r -- _length]), r -- _length ∈ st, ¬ has_classtype(ty0) ∨ tdname+∃(str, ty0 .jtelemtype .class), ∀ j0. ¬ j0 < 0 ∧ ¬ i ≤ j0 → compat(str, st[r -- j0 '], ty0, st) ⊦ r = jvmref, compat(str, st[r -- j '], ty0, addclass(class, fis, st))
