And obtained the following new goals

Proof step 21:
st[r0 -- sks0] = st[r0 -- sks], is_bytevalue(st[r -- mkfs(class, byte_type, fieldvar) ']), fits(r0, sks0, st), fits(r0, sks, st) ⊦ r = jvmref, mkfs(class, byte_type, fieldvar) ' = _length, st[r0 -- sks] .refval = jvmref, sks = [], sks0 = [], sks0 = sks, hasSharing(r0, st[r -- mkfs(class, byte_type, fieldvar) ', byteval(by)]), junkref(str, r0, st)
