What happened:
Reproduce code:

def test_acl_4472(self):
        state = JuicefsMachine()
        v1 = state.init_folders()
        v2 = state.create_file(content=b'', file_name='stsn', mode='x', parent=v1, umask=464, user='root')
        v3 = state.set_acl(default=True, entry=v1, group='group4', group_perm={'x'}, logical=False, mask={'w'}, not_recalc_mask=False, other_perm=set(), physical=False, recalc_mask=True, recursive=True, set_mask=True, sudo_user='root', user='root', user_perm={'r'})
        v8 = state.create_file(content=b'', file_name='qpyt', mode='w', parent=v1, umask=233, user='root')
        v9 = state.copy_file(entry=v2, follow_symlinks=False, new_entry_name='knmh', parent=v1, umask=23, user='root')
        state.open(file=v8, flags=[512], mode=2579, umask=34, user='root')
        state.teardown()
