And obtained the following new goals

Proof step 7:
⊦ compatmode(str, val, st) ↔ val = noval ∨ is_break_mode(val) ∨ val = return(noval, void_type) ∨ is_return_mode(val) ∧ compat(str, val .val, val .type, st) ∨ is_throw_mode(val) ∧ val .refval ≠ jvmref ∧ compat(str, refval(val .refval), val .type, st) ∧ is_subtype(str, val .type, mkclasstype(`java.lang.Throwable' .class))
Proof step 20:
st[_mode] = noval ∨ is_break_mode(st[_mode]) ∨ st[_mode] = return(noval, void_type) ∨ is_return_mode(st[_mode]) ∧ compat(str, st[_mode] .val, st[_mode] .type, st) ∨ is_throw_mode(st[_mode]) ∧ st[_mode] .refval ≠ jvmref ∧ compat(str, refval(st[_mode] .refval), st[_mode] .type, st) ∧ is_subtype(str, st[_mode] .type, mkclasstype(`java.lang.Throwable' .class)), _mode ∈ st, compatstatic(str, st), compatrefs(str, st), compat(str, val, ty, st) ⊦ st[_mode] = return(noval, void_type), st[_mode] = noval, mkfs(class, ty, fieldvar) ' = _length, ty = void_type, is_break_mode(st[_mode]), is_throw_mode(st[_mode]) ∧ st[_mode] .refval ≠ jvmref ∧ compat(str, refval(st[_mode] .refval), st[_mode] .type, st[r -- mkfs(class, ty, fieldvar) ', val]) ∧ is_subtype(str, st[_mode] .type, mkclasstype(`java.lang.Throwable' .class)), is_return_mode(st[_mode]) ∧ compat(str, st[_mode] .val, st[_mode] .type, st[r -- mkfs(class, ty, fieldvar) ', val])
