Which means that the error message is legitimate (e.g. the lambda is capturing a final value that is not initialized). I think reverting back to anon class would be better here.

@forax Thank you for your reply. I tested `t.name != this.names.init` with `final Names names;` just now. The error also occurred. Same as `t.name != names.init`.

And I think that `t.name != names.init` and `t.name != this.names.init` are equal at this situation.
