Can I give lambda a name?

Question

I have nice functional code roughly of next shape (ComponentRegistry.java):

public void doExport() {
    config.exports().forEach((key, type) -> {
        ...
    }
}

The problem with it that when it comes to log4j statements it produces next output:

ComponentRegistry lambda$doExport$1

Where actual method name comes after "lambda" keyword and then there are two hints about anonymous classes ($). It simply not as good as direct method call logging.

I was wondering whether anyone came with way to properly label lambdas in log4j output or stacktraces because it would be awesome.

If you want to give it a name, don't use a lambda (which is explicitly an anonymous function). Instead break it out into its own class.
