Proof step 10 from proof is_obj-no-refval (previous step)

st[r -- _type] .type = mkclasstype(class), st[r -- _type] = typeval(mkclasstype(class)), mkfs(str2 .class, mkclasstype(str0 .class), str1 .field) ' ∈ instfields(class), class+∃(str, class), r -- _type ∈ st, is_typevalue(st[r -- _type]), is_classtype(st[r -- _type] .type), is_obj(r, class, st), r ∈ st ⊦ r = jvmref, is_referencevalue(st[r -- mkfs(str2 .class, mkclasstype(str0 .class), str1 .field) ']), is_abstract(class)

Proof step 9:
st[r -- _type] = typeval(mkclasstype(class)), r ∈ st, is_obj(r, class, st), r -- _type ∈ st, class+∃(str, class), mkfs(str2 .class, mkclasstype(str0 .class), str1 .field) ' ∈ instfields(class) ⊦ r = jvmref, is_abstract(class), is_referencevalue(st[r -- mkfs(str2 .class, mkclasstype(str0 .class), str1 .field) '])
