Proof step 18 from proof junkref-put-other-fieldclass (previous step)

junkref(str, r, st[r0 -- fs ', val]), path∃(str, r, r0, st) ⊦ r0 = jvmref, fs ' = _type, junkref(str, r, st), contains(str, st[r -- _type] .type, fs)

User applied rule cut formula

And obtained the following new goals

Proof step 8:
is_classtype(st[r0 -- _type] .type), junkref(str, r, st[r0 -- fs ', val]), path∃(str, r, r0, st) ⊦ r0 = jvmref, fs ' = _type, junkref(str, r, st), contains(str, st[r -- _type] .type, fs)
Proof step 17:
junkref(str, r, st[r0 -- fs ', val]), path∃(str, r, r0, st) ⊦ is_classtype(st[r0 -- _type] .type), r0 = jvmref, fs ' = _type, junkref(str, r, st), contains(str, st[r -- _type] .type, fs)

Rule argument

[fma-arg: is_classtype(st[r0 -- _type] .type)]
